What is CuAg0.10(OF)?
CuAg0.10(OF) (CR019A) is the highest-silver oxygen-free copper rod grade in the series, supplied annealed (M) and in R200, R240, R280, R320 and R360 tempers. It gives the greatest resistance to thermal softening in the group while retaining oxygen-free purity for critical electronic and vacuum work; annealed values are 70 MPa yield, 225 MPa tensile, 45 % elongation, 45 HB, 391 W/m·K and 101 % IACS, with service to 350 °C. Machinability is 20 and weldability rates 65, so joining usually relies on electron-beam, laser or brazing routes. CuAg0.07(OF) is the lower-cost alternative below 300 °C. CuAg0.10(OF) has a density of 8.94 g/cm³ (0.323 lb/in³), heavier than 90% of copper alloy grades. It melts at 1,075°C (1,967 °F). CuAg0.10(OF) has a yield strength of 70 MPa (10.2 ksi) and a tensile strength of 225 MPa (32.6 ksi) — weaker than 93% of copper alloy grades. Elongation at break is 45% and the elastic modulus is 117 GPa (17 Msi).

Working with CuAg0.10(OF)
Is CuAg0.10(OF) easy to machine?
Gummy and stringy — use sharp, high-positive-rake polished tools, high speed with light-to-moderate feed and flood emulsion; expect ~20 % of AISI 1212 productivity and prefer a cold-worked temper over the annealed state.
Can CuAg0.10(OF) be welded?
Best joined by electron-beam, laser, TIG/MIG with helium and high preheat (400–600 °C for thick sections) or by brazing; being oxygen-free it will not suffer hydrogen embrittlement, but heat-affected zones lose the cold-work strength.
Can CuAg0.10(OF) be formed, bent or molded?
Excellent cold formability in R200 (deep draw, spin, upset, cold head); interanneal 400–600 °C between heavy reductions, and remember the silver raises the recrystallisation temperature so anneals run hotter/longer than for pure Cu.

What surface finishes work on CuAg0.10(OF)?
Not anodisable — deburr and polish easily to a mirror finish, then electroplate Ni/Ag/Au or apply a benzotriazole/lacquer passivation; vacuum parts are typically vapour-degreased and hydrogen- or vacuum-fired.
