How It Works
The outstanding performance of C1100 copper stems from its pure
metallurgical composition. The 99.9% minimum copper content ensures
minimal electrical resistance, allowing for maximum
current-carrying capacity and energy efficiency with minimal heat
generation. The high elongation (>40%) indicates exceptional
ductility, meaning the material can be bent, shaped, and punched
into complex forms without cracking. The specified ultimate
strength range (205-265 MPa) provides the necessary durability and
structural integrity for functional parts. This combination of high
purity for conductivity and inherent malleability for easy
processing makes it a versatile and cost-effective solution for
electrical engineers and fabricators.

Frequently Asked Questions
What is the difference between C1100 and other copper alloys like
brass or bronze?
C1100 is essentially pure copper, optimized for electrical and
thermal conductivity. Brass (copper-zinc) and bronze (copper-tin)
are alloys that offer higher strength, machinability, or corrosion
resistance for specific applications but have significantly lower
conductivity.
Are these copper sheets ready for immediate use, or do they require
processing?
We supply the raw material copper sheets/plates. However, we offer
value-added processing services like precision cutting, bending,
and punching to your specified dimensions and shapes, delivering
components ready for assembly.
What makes this copper suitable for electrical equipment?
The 99.9% purity ensures top-tier electrical conductivity.
Furthermore, its excellent elongation allows it to be formed into
tight contacts and connectors without work-hardening or cracking,
ensuring long-term reliability in electrical systems.
Can I order custom sizes?
Absolutely. The width and other dimensions can be fully customized.
