Construction:

Bare copper, solid or stranded. Tinned copper available upon request.
Available in tempers hard, medium-hard, or soft.
Stranded conductors are concentrically stranded in hard and medium-hard tempers and are Combination Unilay stranded in the soft-drawn temper.

Applications and Features:

Solid and stranded copper are suitable for grounding and distribution applications. Stranded conductors offer greater flexibility (classes B, C and D). Compact stranded copper offers smaller conductor OD.

Specifications:

ASTM B1 Hard-Drawn Copper

ASTM B2 Medium-Hard Drawn Copper Wire

ASTM B3 Standard Specification for Soft or Annealed Copper Wire

ASTM B8 Concentric-Lay-Stranded Copper Conductors

ASTM B33 Standard Specification for Tin-Coated Soft or Annealed Copper Wire

ASTM B496 Compact Round Concentric-lay-standard copper
