Key Factors to Consider When Choosing Fabrication Materials
Must Considerations for material selection in your fabrication project are given below:
Durability
First of all, consider the durability of the material when choosing it to use in fabrication. Strong materials resist wear and tear over time. You don’t want something that’ll break down after a few uses, right? Durability helps you to reduce costs of repair and replacement in the future.
Corrosion Resistance
Corrosion resistance is critical when parts will be exposed to moisture, and chemicals or might be used outdoors. Imagine using a material that rusts after a few months – not ideal! Materials like stainless steel and aluminum do not corrode easily. Therefore, the material retains a good appearance and high performance for many years even in abrasive conditions.
Strength-to-Weight Ratio
Sometimes, you need a material that’s both strong and lightweight. For instance, in manufacturing parts for an airplane, every pound matters. Materials with a good strength-to-weight ratio give you the best of both worlds: they’re strong but not very dense which is ideal for things like car and plane parts.
Workability & Machineability
Workability is all about how easily you can shape the material. Aluminum is manageable, and you can pierce, weld, or form it easily. As a rule, the easier the material is to manipulate, the faster the fabrication process. Indeed, it is a double boon for cost and efficiency.
Cost Effectiveness
While you want high-quality materials, you also need to keep it budget-friendly. Affordable materials make it possible to achieve resonant performance at a reasonable cost. You don’t want to be spending a lot of your money on products that will give you little in the long run. So, it’s all about balancing between two extremes.
Formability
Formability determines how easily the material can be shaped or formed. Some materials, like mild steel, are super easy to shape into complex designs. When your project requires curves, fancy cutting, or designs, be sure to go for the type of material that you can manipulate in various ways.
Recyclability
Want to be more eco-friendly? Recyclable materials are the way to go. For instance, aluminum. Using recyclable material doesn’t only help save the environment but it also assists in cutting costs and helps make your business appear more environmentally friendly.
Flexibility
The best way to look at flexibility is how easily a material can bend without fracturing. Certain projects call for materials that should be capable of withstanding stress, and impact. Meanwhile, do not break. For example, spring steel is generally a more flexible option. It is good for items such as springs and other bending objects. But, it cannot afford to snap.
