Copper Alloys

ETP commercial high-conductivity copper vs OFE high-purity oxygen-free copper (<5 ppm O2) for hydrogen atmosphere brazing, glass-to-metal seals, and vacuum electronics.

Selection between high-conductivity electrolytic tough pitch copper and oxygen-free copper for welding and high-temperature brazing operations.

Comparison of high electrical conductivity busbar copper versus phosphorus-deoxidized plumbing, HVAC, and refrigeration tubing.

Trade-off between electrical and thermal conductivity of unalloyed copper versus high-speed automated lathe machinability of leaded brass.

Selection between low-phosphorus (DLP) and high-phosphorus (DHP) deoxidized coppers for thermal transfer, brazing, and cold forming.

Fabrication selection between deep-drawing cold ductility (70/30 brass) and automated high-speed turning machinability (leaded brass).

Comparison of 5% tin and 8% tin phosphor bronzes for spring contact, fatigue endurance, and sliding wear resistance.

Marine seawater piping and condenser alloy evaluation: 90/10 copper-nickel versus 70/30 copper-nickel for marine fluid handling and corrosion endurance.

Cast bronze bearing selection: anti-friction sleeve bearing bronze (SAE 660) versus high-strength aluminum bronze (9C) for heavy load and wear components.
