CW004A Copper (C101)

With impressively high thermal conductivity, C101 copper, also known as CW004A and Electrolytic Tough Pitch Copper (ETP), is a popular choice for a wide variety of electrical components and conductors. CW004A copper is commonly used in the engineering industry for a large selection of applications. The C101 copper alloy is typically produced as HDHC, hard-drawn, high connectivity. This offers high ductility and impact strength which makes it an extremely versatile and useful material. At Prestige Metal Supplies, our supply of C101 is available as copper sheet as well as copper bar such as flat bar, hexagonal bar, hollow bar, round bar and square bar forms.

C101 Copper Properties

Electrolytic tough pitch copper (ETP) C101/ CW004A is known for its excellent electrical conductivity and aesthetic appearance. C101 is highly workable in hot and cold temperatures making it a preferred choice for electrical, electronic and architectural applications. ETP copper exhibits exceptional corrosion resistance and can be easily fabricated, making it an ideal material for critical applications that require reliability and longevity. Its excellent thermal conductivity and ease of soldering and brazing make it a versatile choice for a wide range of industrial and manufacturing processes.

C101 Copper Shapes and Forms

At Prestige Metal Supplies, we stock a range of copper forms and shapes suitable for a wide variety of applications across many industries. Our supply of C101 is available in copper bar and rod in solid and cylindrical shapes in varying diameters. Our copper rods and bars are available in 3 mm – 254mm diameters and can be cut to your specifications as a part of our in-house services.

Copper Plate and Copper Sheet

At Prestige, we are also leading copper sheet and copper plate suppliers. Copper plate and sheet are commonly used in electrical applications, architectural projects and industrial manufacturing due to their excellent conductivity and malleability. Our range of copper plate products are accessible to our customers in incremental sizes tailored to meet diverse engineering applications. As well as having excellent weldability, these copper plates boast superior fatigue resistance and overall strength, delivering outstanding corrosion resistance while being easily fabricated. The main thing that differentiates our cw004a copper plate and sheet is the thickness with the plate form being thicker than copper sheet. Currently, we hold copper plate from 3mm to 150mm thick and we offer in-house plate sawing services for your convenience. The applications of copper plate and sheet span a wide spectrum including boilers, radiators, kick plates, architectural fittings and electrical conductors.
