- Gas Metal Arc Welding or MIG welding (GMAW/MIG)
- Resistance Welding
- Forming and bending
Aluminum can be shaped and bent utilizing various forming procedures, for example:
- Press brake bending
- Roll forming
- Stretch forming these technologies helps to make complex structures without sacrificing the strength of the material.
- Machining
Machining includes removing materials to make shapes and dimensions. Standard machining methods are:
- CNC milling
- Turning
- Drilling
- Extrusion
Extrusion is when aluminum is forced through the die to create long, uniform cross-sections. It is usually used to manufacture structural parts and tubing.
- Casting
Aluminum casting includes pouring molten aluminum within a mold to make intricate parts. The main types of aluminum casting include:
- Sand casting
- Die casting
- Permanent mold casting
