Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening fasteners, which can strip threads or deform the aluminum.Use a torque wrench to tighten fasteners to the manufacturer's recommended specification for Aluminum 6061, typically lower than for steel.
Using steel nuts and washers directly against aluminum, leading to galvanic corrosion.Employ insulating washers (e.g., nylon or neoprene) or ensure all fasteners and associated hardware are also made of compatible aluminum alloys or appropriately coated materials.

Common Applications

  • Marine hardware and pipe support
  • Lightweight structural framing
  • Aerospace and automotive components
  • Corrosion-resistant conduit and pipe clamping

⚠️ Engineering Warnings

  • Aluminum 6061 has lower tensile strength than steel; ensure load ratings are not exceeded.
  • Avoid exposure to highly alkaline or acidic environments that can degrade aluminum.
