Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening aluminum fasteners leading to thread stripping or component damage.Always use a torque wrench and adhere to manufacturer-specified torque values, which are typically lower for aluminum than steel.
Using standard steel tools without proper care, which can scratch or damage the aluminum surface.Employ tools with smooth surfaces or protective coatings, and handle with care to prevent cosmetic damage.

Common Applications

  • Aerospace structural components
  • Automotive chassis and body assembly
  • Marine hardware and fittings

⚠️ Engineering Warnings

  • Aluminum 6061 is susceptible to galvanic corrosion when in direct contact with dissimilar metals in a corrosive environment.
  • Avoid using in applications requiring high shear strength or extreme temperatures where steel or stainless steel may be more suitable.
