Materials


    Categorical symbols we use to describe copper and copper-alloy【JIS H3100・H3250 H3300】
Name Alloy Number Form Symbol Characteristics and Uses
Oxygen-free copper C1020 Plate C1020P This material contains excellent conductivity of electricity and heat, also excellent malleability and draw excellently. Weldability, corrosion resistance and weather resistance are also excellent. It will not cause hydrogen embrittlement when it is heated to a high temperature in the reducing atmosphere. It is used for electricity and chemical industry.
Ribbon C1020R
Extruded bar C1020BE
Drawn bar C1020BD
Pipe (standard) C1020T
Pipe (particular) C1020TS
Phosphorous-deoxidized copper C1220 Plate C1220P This material contains excellent malleability and draw well. It also contains good Weldability, corrosion resistance, weather resistance and good conductivity of heat. It will not cause hydrogen embrittlement when it is heated to a high temperature in the reducing atmosphere. It is used for bath boiler, water heater, gasket, architecture and chemical industry.

    Categorical symbols we use to describe copper and copper-alloy casting 【JIS H5120】
Category Symbol (old symbol) Characteristics and Uses
Brass casting class T CAC201(YBSC1) This material permits soldering easily. It is used for flanges, electrical parts, decorative articles, etc.
Brass casting class U CAC202(YBSC2) This material is comparatively easy to cast among brass casting materials. It is used for electrical appliances, gauge parts, general device parts, etc.
Bronze casting class V CAC403(BC3) This material contains good pressure resistance, abrasion resistance, mechanical property, and its corrosion resistance is better than that of CAC402(BC2). It is used for bearing, sleeve, bushing, pump body, impeller, valve, gear, marine porthole, electric motor-driven parts, general machine parts, and so on.
Bronze casting class Y CAC406(BC6) Pressure resistance, abrasion resistance, machinability and castability are excellent. It is used for valve, pump body, impeller, hydrant, bearing, sleeve, bushing, general machine parts, landscape casting, fine arts casting and so on.
Aluminum bronze casting class T CAC701(AlBC1) This material is strong, tenacious and hard to bend. It contains good corrosion resistance, heat resistance, abrasion resistance and low-temperature properties. It is used for acid-proof pump, bearing, bushing, gear, valve seat, plunger, rolls for paper-making, etc.
Aluminum bronze casting class U CAC702(AlBC2) This material contains high degree of toughness, good corrosion resistance and abrasion resistance. It is used for small-sized marine propeller, bearing, gear, bushing, valve seat, impeller, bolt, nut, safety tool, bearing for stainless steel and so on.
Aluminum bronze casting class V CAC703(AlBC3) This material is suitable for large-scale casting and is extremely strong, and contains excellent corrosion resistance and abrasion resistance. It is used for marine propeller, impeller, valve, gear, pumping parts, device parts for chemical industry, bearing for stainless steel, machine parts for food food processing and so on.
