Differences between Ferrous and Non-Ferrous Metals

When it comes to mechanical engineering and steel fabrication, one of the most commonly asked questions from clients are ‘what is the difference between ferrous and non-ferrous metals?’ The experts at Rider Tool & Manufacturing Co., one of the most trusted contract manufacturing companies in Ontario, provide an explanation below. 

Ferrous Metals 

The main difference between ferrous metals and non-ferrous metals is the fact that ferrous metals contain iron and non-ferrous metals do not. Because of this, each type of metal has a number of specific applications to which they are better suited. Many ferrous metals, for example, provide superior durability and tensile strength, with the most common ferrous metals being alloy steel, carbon steel, cast iron and wrought iron. Ferrous metals are also magnetic. 

They are most commonly used in the construction industry and are also employed in the manufacture of things like cars, railroad tracks and more. The only down-side to ferrous metals is that they are quite vulnerable to corrosion due to their high carbon content (with the exception of stainless steel and wrought iron which are both rust-resistant). 

Non-Ferrous Metals

Non-ferrous metals do not contain iron and are usually corrosion resistant and more malleable than ferrous metals. Gold, silver, tin, aluminum, copper, lead and zinc are all non-ferrous metals. 

Non-ferrous metals are not magnetic and are often employed in the manufacture of electronics and wiring because of this. These types of metals are also often used to produce things like gutters, roofing, signage and liquid pipes.

A Guide to Powder Coating and Wet Coating in Metal Fabrication

It is important to coat metals in order to make them durable. The coating reduces the chances of rusting and the day-to-day wear-and-tear of the metals. Most metal fabrication companies use either powder or wet coating for metals.

Metal Coating and the Environment

Metal coating practices have now become more-friendly to the environment than before. Today, the chemicals used in wet coating by either contract manufacturing companies or the manufacturing companies are fast drying – hence less pollution. Emissions from powder coating are not as high and can also be recycled and this makes them very friendly to the environment right here in Oshawa, Ontario.

The Difference between Powder and Wet Coating

Coating generally means painting. 

Wet Coating

In wet coating, liquid paint is applied on the metal by the use of a pressurized vessel or a spray gun. This coating is recommended for metals that cannot undergo any form of heating or metals that require a specific colour. 

Powder Coating

Powder coating, on the other hand, refers to the electrostatic application of dry powder on the metal. Unlike wet coating, powder coating does not require a carrier. Once the powder has been applied to the metals, they are baked in an oven at 450 degrees. The heat transforms the powder into a liquid and then a solid form resulting in a thick and solid coating that is much more durable than wet coating.

Silos and Bins: Steel vs. Concrete

Just a few of the many ways in which one can store coal, silage, wood chips, grains and many other items is by making use of bins and silos. These two methods of storage are the most common. In as much as both of these are used for storage, they are also quite different.

Differences between Steel and Concrete 

Here is what makes the two different: 

Design: 

Silos and bins that are manufactured from steel have higher storage capacity and better aeration than those made from concrete. Also, when constructed wide and short, their resilience to outside temperatures is improved. When it comes to the foundation of the silos, concrete structures require a compact one due to its weight, and this makes them more expensive to construct. The best thing about steel is that you can have a custom metal fabrication design.

Cost: 

Constructing a concrete silo is quite different when compared to constructing a steel one. It requires more labour and time, and this translates to a higher cost of construction. Steel silos, on the other hand, can be fabricated and constructed in a shorter time. Steel fabrication is today a growing trend in storage building.

Construction: 

Concrete structures must be built on site while steel can be fabricated in a factory. This makes constructing a steel bin or silo a little easier than a concrete one. While constructing, it is important to consider factors like the weather and convenience. Metal fabrication is quite common in Oshawa, Ontario today.

When Is the Right Time to Replace a Pressure Vessel?

Pressure vessels are essential to companies in all industries. They need to be kept up to date and up to code for both a company’s optimal operations and its employees’ safety. However, how do we know when a pressure vessel has run its course? We have the answers to your pressure vessel and metal fabrication questions!

Signs That You Need to Replace Your Pressure Vessel:

When a pressure vessel is leaking, its bladder has failed or it has become waterlogged, you may notice some issues which may include the following:

    • Reduced water pressure, especially at fixtures on the second floor
    • Unstable water pressure as the pump cycles on and off
    • A pump that runs less than a minute in order to pressurize the tank
    • A vessel that cycles on and off frequently
    • A vessel that remains running
    • Water leaks at the pressure vessel
    • Visible corrosion on the exterior of the vessel
    • Excessive air in the plumbing system as faucets and fixtures are used
    • Low pressure at the pressure gauge

What to Do If Your Pressure Vessel Needs to be Replaced:

If you notice any of these problems with your steel fabrication and pressure vessel, it may need to be replaced. Have a professional inspect it as soon as possible to avoid causing damage to the pump or premature failure. It can be expensive to replace, especially submersible models, so it’s important that you get it fixed or replace it before more damage is done and the extra cost is incurred.

Questions to Ask a Professional When Replacing Your Pressure Vessel:

    • Was it designed, custom fabricated and constructed according to the ASME Code or other applicable code? Does the vessel code label or stamp prove this?
    • Is the operating pressure and size of the vessel known and clearly displayed?
    • Is the vessel inspected periodically? What are the criteria for inspection frequency? When was it last inspected externally? When was it last inspected internally?
    • Did the inspection discover thinning of walls due to corrosion, holes, leaks, stress corrosion cracking, embrittlement or any other defects?
    • Have the pressure relieving devices been tested regularly? When was the last time?
    • If the vessel was repaired, did the changes in operating conditions alter relief device settings?

custom metal fabrication

Tolerance: A Critical Factor in Custom Metal Fabrication

There are industry standards for the maximum allowable distortion, which is known as tolerance, for each type of alloy used in standard and custom aluminum extrusion. Tolerances are crucial to the mechanical engineering manufacturing process as they will not only determine how well a part will fit in final production, but also as how stable the final product will be. Tolerances can refer to mechanical fit, fit up (i.e. proper alignment of holes for assembly), deviations from straightness or accuracy of assembly. It is the most important consideration for decision makers in their custom metal fabrication. Below, we take a look at the importance of tolerance in custom metal fabrication.

Why Is Tolerance Important in Custom Metal Fabrication?

  • Risk Management

Checking the correct tolerances is some of risk management’s most important duties. A well-trained risk management team will not only mitigate the risk associated with poor tolerances but will also dramatically reduce the number of faulty parts in a production cycle. Risk management gives metal fabricators the ability to reflect on their processes and assess the way in which improvements can be made. Risk management can run through parts faster and be more effective if tolerances are optimized.

  • Choosing the Right Fit for Optimization

We work with nominal thicknesses in custom fabrication, so it is important to know the thickness tolerance on the material you choose in order to know if the final product will be suitable for your application. It is important when working with sheet metal that you factor in finish tolerances. If you add a finish such as powder-coat, you add more thickness, and this should be factored into your design at the beginning.

  • Precision

The accuracy of the machinery that processes raw materials contributes to what is practical in terms of precision in sheet metal. Manufacturing tolerances are limited by the physics of rolling hot metal to create sheet stock. Tolerances for precision work such as laser cutting, machining and forming will have little room for error. More precision requires greater consistency in the tooling setup for blanking and bending of the sheet metal parts. It is important to use a correct guideline with regard to tolerances to ensure the correct precision is determined.
