Working with IC-Ag99.95-H02
Is IC-Ag99.95 easy to machine?
Very gummy — use sharp polished high-rake HSS/carbide, high speed, light depth and generous lubrication to avoid smearing and built-up edge; collect all swarf for refining.
Can IC-Ag99.95 be welded?
Resistance, laser and micro-TIG welding work but the 429 W/m·K conductivity demands short, high-energy pulses; more commonly joined by silver brazing or soft soldering.
Can IC-Ag99.95 be formed, bent or molded?
Outstanding cold formability in O temper (deep draw, spin, roll-bond, draw to <25 µm wire); anneal 550–650 °C in slightly reducing or inert atmosphere and avoid oxygen/hydrogen embrittlement cycles.
What surface finishes work on IC-Ag99.95?
Not anodisable; electropolish or buff to a mirror finish, then rhodium/gold plate or apply anti-tarnish lacquer/benzotriazole treatment to suppress sulfide blackening.

IC-Ag99.95-H02 — frequently asked
What is IC-Ag99.95-H02 used for?
IC-Ag99.95-H02 is typically used for electrical contacts, catalysts and alloy feedstock. In short: highest IACS on file; contact and catalyst purity; very soft, non-structural.
What is the yield strength of IC-Ag99.95-H02?
IC-Ag99.95-H02 has a typical yield strength of 180 MPa (26.1 ksi) and a tensile strength of 240 MPa (34.8 ksi) — weaker than 59% of precious metal grades. Strength varies by condition: see the 5 listed tempers.
Is IC-Ag99.95-H02 easy to machine?
Reasonably — machinability is rated fair (50/100, better than 74% of precious metal grades). Very gummy — use sharp polished high-rake HSS/carbide, high speed, light depth and generous lubrication to avoid smearing and built-up edge; collect all swarf for refining.
Can IC-Ag99.95-H02 be welded?
Yes — weldability is rated very good (75/100). Resistance, laser and micro-TIG welding work but the 429 W/m·K conductivity demands short, high-energy pulses; more commonly joined by silver brazing or soft soldering.
What surface finishes work on IC-Ag99.95-H02?
Not anodisable; electropolish or buff to a mirror finish, then rhodium/gold plate or apply anti-tarnish lacquer/benzotriazole treatment to suppress sulfide blackening.
Can IC-Ag99.95-H02 be formed, bent or molded?
Outstanding cold formability in O temper (deep draw, spin, roll-bond, draw to <25 µm wire); anneal 550–650 °C in slightly reducing or inert atmosphere and avoid oxygen/hydrogen embrittlement cycles.
What is the maximum service temperature of IC-Ag99.95-H02?
IC-Ag99.95-H02 is rated for continuous use to about 180°C (356 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between IC-Ag99.95 Cast and IC-Ag99.95-H08?
Cast is the default condition — standard 1 kg / 15 kg refined ingot for remelting, alloying, electrolyte or chemical feedstock. H08: only for fine spring wire and probe/contact wire where peak strength matters more than ductility. Yield strength is 45 MPa in Cast versus 320 MPa in H08.
