Electronics

Appications

Alloys

  • 1070,2011,2012,2017,2024,3003,5052,6061,6063 ~

Characteristics

3xxx alloys

Merit
  • Good extrudability, weldability and resistance to corrosion
  • Good for complex shape extrusion
Demerit
  • Relatively lower strength (Similar to 1xxx)

7xxx alloys

Merit
  • The highest strength
  • Good weldability
Demerit
  • Poor corrosion resistance (Clading & anodizing required for protection)

Specification

3xxx alloys

  • Pipe : Ф9 ~ Ф80
  • Straightness : Under 1mm / 1000 mm
  • Inner/Outter diameter tolerance: ±0.1 mm
  • Thickness eccentricity: ± 0.1mm

7xxx alloys

  • Rod : Ø4.5 ~Ø45
