What is CuAg0.10P?
CuAg0.10P (CR016A) is the highest-silver phosphorus-deoxidized copper rod grade in the series, available annealed (M) and in R200, R240, R250, R290 and R360 tempers. It is chosen where welded or brazed conductors must keep strength after heat exposure: the listed condition shows 200 MPa yield, 265 MPa tensile, 25 % elongation, 68 HB (25 HRB), 385 W/m·K and 99 % IACS with service to 300 °C, and it scores 90 for weldability. The trade-off is low machinability (22) and reduced ductility versus the annealed silver coppers. CuAg0.07P is the nearest option when more forming reserve is needed. CuAg0.10P has a density of 8.94 g/cm³ (0.323 lb/in³), heavier than 90% of copper alloy grades. It melts at 1,065°C (1,949 °F). CuAg0.10P has a yield strength of 200 MPa (29 ksi) and a tensile strength of 265 MPa (38.4 ksi) — weaker than 54% of copper alloy grades. Elongation at break is 25% and the elastic modulus is 120 GPa (17.4 Msi).

Working with CuAg0.10P
Is CuAg0.10P easy to machine?
Gummy and low-rated (~20 % of AISI 1212): use sharp positive-rake polished tools, high speed, low feed and generous soluble-oil coolant to avoid built-up edge.
Can CuAg0.10P be welded?
Excellent for GTAW/GMAW, resistance and induction welding — low residual P means no hydrogen embrittlement; preheat 150–400 °C on thick sections because of high heat conduction.
Can CuAg0.10P be formed, bent or molded?
Very ductile in R200; cold heads, bends and deep-draws readily, with interstage anneals at 400–550 °C (silver keeps annealing needs above plain copper).

What surface finishes work on CuAg0.10P?
Not anodisable; solders and brazes exceptionally well, takes electroplated tin/silver/nickel readily, and polishes to a bright finish that requires lacquer or passivation to stop tarnish.

CuAg0.10P — frequently asked
What is CuAg0.10P used for?
CuAg0.10P is typically used for high-temperature brazed conductors, welded busbar assemblies and commutator risers. In short: best weldability of the series; highest-silver deoxidized copper; 99 % IACS after brazing.

CuAg0.10P has a typical yield strength of 200 MPa (29 ksi) and a tensile strength of 265 MPa (38.4 ksi) — weaker than 54% of copper alloy grades. Strength varies by condition: see the 6 listed tempers.
Is CuAg0.10P easy to machine?
Not especially — machinability is rated poor (22/100, worse than 94% of copper alloy grades). Gummy and low-rated (~20 % of AISI 1212): use sharp positive-rake polished tools, high speed, low feed and generous soluble-oil coolant to avoid built-up edge.
