Precious Metal AgCu10 vs Argentium 935

Precious Metal · grade comparison

Precious Metal AgCu10 and Argentium 935 are both precious metal grades. AgCu10 is the stronger of the two: yield strength 115 MPa (16.7 ksi) against 80 MPa (11.6 ksi) for Argentium 935, about 44% more; tensile strength follows at 285 MPa (41.3 ksi) vs 260 MPa (37.7 ksi). In exchange, Argentium 935 is the more ductile: elongation 45% versus 35% for AgCu10, and AgCu10 is harder (60 HB vs 48 HB). AgCu10 runs hotter in service (250°C vs 200°C continuous). On the shop floor, Argentium 935 welds better (excellent vs good).

AgCu10Choose it when strength drives the design, or when the part sees heat.

Argentium 935Choose it when the part is bent, formed or impact-loaded, or when it will be welded.
