Working with Pd60Ag40-H06
Is Pd60Ag40 easy to machine?
Soft and gummy — use sharp, high-rake carbide or HSS tools, light feeds, flood lubrication, and collect all swarf for refining.
Can Pd60Ag40 be welded?
Resistance, laser and micro-TIG welding of contact rivets and blades work well; avoid sulfur- or halide-bearing fluxes.
Can Pd60Ag40 be formed, bent or molded?
Excellent cold formability in the annealed state (deep drawing, heading, fine wire drawing); interanneal at 700–850 °C in inert or reducing atmosphere between heavy reductions.
What surface finishes work on Pd60Ag40?
Takes a mirror polish; usually used bare, sometimes gold, rhodium or ruthenium flash-plated to reduce organic-film (brown powder) build-up on low-level contacts. Not anodizable.

Pd60Ag40-H06 — frequently asked
What is Pd60Ag40-H06 used for?
Pd60Ag40-H06 is typically used for electrical contacts, thick-film resistor pastes and relay contacts. In short: most formable Pd alloy; lower-cost palladium contact; deep-drawable contact metal.
What is the yield strength of Pd60Ag40-H06?
Pd60Ag40-H06 has a typical yield strength of 780 MPa (113 ksi) and a tensile strength of 830 MPa (120 ksi) — stronger than 100% of precious metal grades. Strength varies by condition: see the 6 listed tempers.
Is Pd60Ag40-H06 easy to machine?
Reasonably — machinability is rated fair (48/100, better than 71% of precious metal grades). Soft and gummy — use sharp, high-rake carbide or HSS tools, light feeds, flood lubrication, and collect all swarf for refining.
Can Pd60Ag40-H06 be welded?
Yes — weldability is rated good (60/100). Resistance, laser and micro-TIG welding of contact rivets and blades work well; avoid sulfur- or halide-bearing fluxes.
What surface finishes work on Pd60Ag40-H06?
Takes a mirror polish; usually used bare, sometimes gold, rhodium or ruthenium flash-plated to reduce organic-film (brown powder) build-up on low-level contacts. Not anodizable.
Can Pd60Ag40-H06 be formed, bent or molded?
Excellent cold formability in the annealed state (deep drawing, heading, fine wire drawing); interanneal at 700–850 °C in inert or reducing atmosphere between heavy reductions.
What is the maximum service temperature of Pd60Ag40-H06?
Pd60Ag40-H06 is rated for continuous use to about 230°C (446 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between Pd60Ag40-O and Pd60Ag40-H06?
O is the default condition — standard stocked condition for stamping, deep drawing, contact rivet heading and wire drawing. H06: maximum-strength spring temper for relay spring contacts and probe wire. Yield strength is 180 MPa in O versus 780 MPa in H06.
