Material selectionWhat Specialty Materials Work Best for Electric Car Components?

  • Aluminum Alloys
  • Stainless Steel and Specialty Steel
  • Nickel and High Temperature Alloys
  • Copper Alloys

Aluminum Alloys

There is a great deal of aluminum alloys in commercial electric vehicles, trucks, and buses. Most aluminum alloys offer high weight to strength ratios, corrosion resistance, formability, and favorable pricing.

Below are some of the grades in stock:
Aluminum 2011
Aluminum 4032
Aluminum 6061
Aluminum 6063
Aluminum 7075-T7651

Stainless Steel and Specialty Steel 

Stainless steel alloys have found increasing usage in electric car components that require great strength but can handle the increased weight. The high corrosion and temperature resistances found in stainless steel make it suitable for a range of electric car parts, including actuators, fasteners, and landing gear components.

Below are some of the grades in stock:
AISI 303
AISI 304
AISI 316
AISI 630

Nickel and High Temperature Alloys

In electric vehicles, nickel steel alloys are extremely popular. This demand is due to its increased hardness, tensile strength, and elastic limit, all without reduced ductility. It also maintains strength at elevated temperatures as high as 1,050˚C to 1,200˚C. You find nickel alloys in different electric vehicles including, bolts, terminals, keys, clevises, etc. The nickel-based super alloys Inconel and Hastelloy are also used extensively.

Below are some of the grades in stock:
Nickel-Chromium Alloys – Inconel®
Inconel 600
Inconel 617
Inconel 625
Inconel 718

Nickel-Molybdenum-Chromium Alloys – Hastelloy®
Hastelloy C276

Copper Alloys

With copper’s outstanding conductivity, it is the metal of choice for wiring in most electric car electrical systems. It is also widely used for precision bearings, bushings, tube fittings, and gears.

Below are some of the grades in stock:
Copper C3600
Copper C3602
Copper C3604
Copper C4926 (Lead Free)
