Copper C101 (ETP) — Machining & Properties
Typical properties, what Copper C101 (ETP) is like on a machine tool, what it gets used for, and the tolerance and finishes we hold on it — from a shop that actually machines it, not a datasheet aggregator. Every figure here drives our own calculators.
Machining Copper C101 (ETP)
Machinability is rated good — a well-behaved material to machine with correctly chosen tooling and parameters. Brass CZ121 and CZ131 are among the most economical materials to machine — their outstanding chip-breaking behaviour allows high speeds and excellent surface finish. Beryllium copper must be machined with appropriate respiratory controls in place.
Our standard achievable tolerance on Copper C101 (ETP) is ±0.010mm under normal conditions, with tighter tolerances on critical features agreed at quotation. Standard finishes: As machined, tin plate. Full material traceability with MTR and CoC documentation on every order.
Typical applications
Electrical contacts, heat sink plates, RF shielding, busbars.

Copper C101 (ETP) — FAQ
What is the density of Copper C101 (ETP)?
8.96 g/cm³ (typical). That is 8960 kg/m³ — our metal weight calculator uses exactly this figure for Copper C101 (ETP).
What is the tensile strength of Copper C101 (ETP)?
Typically 220 MPa. Treat it as a typical value, not a specification — the Material Test Report supplied with your order states the actual certified figures for the batch.
Is Copper C101 (ETP) easy to machine?
Its machinability is rated good — a well-behaved material to machine with correctly chosen tooling and parameters.
What is Copper C101 (ETP) used for?
Typical applications: Electrical contacts, heat sink plates, RF shielding, busbars.
What tolerance can be held when machining Copper C101 (ETP)?
Our standard achievable tolerance on Copper C101 (ETP) is ±0.010mm under normal conditions (ISO 2768-f general tolerancing). Tighter tolerances on critical features can be agreed at quotation for specific geometries.
Can Dalloway machine Copper C101 (ETP)?
Yes — we machine Copper C101 (ETP) in-house on 3, 4 and 5-axis milling and CNC turning, from single prototypes to production, with MTR and CoC documentation standard. Typical finishes: As machined, tin plate.
