How to Choose the Right Metal for Your Custom Enclosure

When you are designing an enclosure, choose what metal to use. With metal parts manufacturing, there comes a wide range of metal parts. If you want to design an enclosure, you want perfection in everything. This will come by choosing the right metal for your enclosure.

Metal parts stamping is referred to as pressing. It is a low-cost, high-speed manufacturing process that can produce a high volume of the same metal components. The process of metal stamping includes:

  • Punching
  • Blanking
  • Embossing
  • Coining
  • Bending
  • Flanging

Things to Consider For Choosing the Right Metal:


Most metal options are priced almost the same. Stainless steel is substantially more expensive because of the nickel and chromium content. More cost-effective metals may be used for a variety of indoor applications while also being incredibly robust, and finishing options can provide corrosion protection. If cost is the most important factor for you, you have a lot of choices.

Environmental Conditions:

If your enclosure is going to be residing outside, you will need to choose corrosion-resistant metal with the appropriate finishes. If your enclosure will be partially or completely submerged in water (particularly salt water), extra protection will be required.

Corrosion resistance is one of the most important considerations when deciding which metal to apply for your enclosure. When metals are subjected to:

  • Heat
  • UV radiation
  • Harsh chemicals,
  • Moisture

They corrode at different speeds.


Of course, the function should always take priority over designing an enclosure when prototyping. Having a visually pleasing and professional-looking prototype may be the deciding factor in gaining acceptance and buzz from:

  • Colleagues
  • Stakeholders
  • Future buyers

With aesthetics, each metal material option has its own set of advantages, and there is a wide range of custom finishing options to help take your design to the next level. If the same finish applies to all metals, they will be visually indistinguishable.


For determining the most suitable material for your custom enclosure, weight is the most important factor. Most of the people who create custom enclosures got to take measurements out in the field. The lighter the enclosure, the better the results! The weight of your enclosure should be your main consideration. When you consider the additional weight of your electronics and components, your final product is completed.

Some of the Common Metals Used:


  • Lightweight metal.
  • Offer corrosion resistance.
  • Fine finishing options.
  • Lower stiffness than steel.

Stainless Steel:

  • High strength and stiffness.
  • High corrosion resistance.
  • Can be powder coated or left unpainted.
  • Good for general-purpose enclosures.


  • It is soft, ductile, and flexible metal.
  • High thermal and electrical conductivity.
  • It is ideal to form an enclosure.
  • It is expensive
