Advanced Metals. Demanding Applications.
When a general-purpose metal is not enough, the grade matters. These materials are chosen for a specific property — conductivity, machinability, strength or corrosion resistance — documented against the relevant standard or producer data.
C10100 · Oxygen-Free Electronic
Copper (ETP, Oxygen-Free & DHP)
≥ 101% IACS
minimum conductivity, annealed
Oxygen-free grades reach ≥ 101% IACS and resist hydrogen embrittlement during brazing.
Used for: Busbars and bus conductors; Electrical conductors, terminals and connectors.
C14500 · Tellurium Copper
Tellurium Copper
85 vs 20
machinability rating vs oxygen-free copper
Machines far better than pure copper (rating 85 vs 20) while keeping 93% IACS.
Used for: Machined electrical connectors and terminals; Switch and motor parts.
C17200 · Copper Beryllium
Beryllium Copper
1.80–2.00% Be
age-hardenable to very high strength
Heat-treatable to very high strength while retaining useful conductivity.
Used for: Springs, Belleville washers and retaining rings; Electrical connectors, relay and switch parts.
C70600 · Copper-Nickel 90/10
Cupro-Nickel 90/10
9–11% Ni
with 1.0–1.8% Fe for seawater service
Seawater corrosion and biofouling resistance for marine piping and condensers.
Used for: Seawater piping systems and fittings; Condensers, evaporators and heat-exchanger tubes.
Alloy 625 · UNS N06625
Inconel® Nickel-Chromium Alloys
20–23% Cr · 8–10% Mo
for severe corrosive environments
Strength and corrosion resistance from cryogenic to high-temperature service.
Used for: Furnace retorts, muffles and heat-treating fixtures (600); Seawater and chemical-process components (625).
Grade 2 · UNS R50400
Titanium
10–80 °C
range in which it is virtually immune to wet chlorine
Grade 2 for corrosion resistance, Grade 5 (Ti-6Al-4V) for high strength.
Used for: Chemical-process equipment in chloride media; Seawater-service components.
