ASTM B135/B135m Cu Alloy No. 220 C22000 Cu Zn H90 H95 H96 Pipes Light Annealed 4 Inch Price 90cu-10zn Seamless Brass Tube for Water Supply and Drainage Pipe

ASTM B135/B135M Cu Alloy No. 220 (C22000) seamless brass tubes are supplied in light annealed temper for water supply and drainage piping systems. The 90Cu-10Zn composition delivers a balanced combination of strength, thermal and electrical conductivity, and corrosion resistance, making these 4-inch brass tubes a dependable choice for plumbing, construction, and industrial fluid handling applications.

C22000 is a standard copper-zinc brass alloy. Its controlled chemistry supports consistent mechanical performance and reliable forming characteristics.

• Copper (Cu): 89.0% – 91.0%
• Zinc (Zn): balance
• Lead (Pb): ≤ 0.05%
• Iron (Fe): ≤ 0.05%
• Total other impurities: ≤ 0.3%

Mechanical values depend on heat treatment condition and processing method. Typical figures for C22000 are:

• Tensile strength: up to 200 MPa
• Yield strength: up to 150 MPa
• Elongation: up to 15%

With high strength, excellent electrical and thermal conductivity, and good corrosion resistance, C22000 brass tube serves a wide range of industries:

• Construction: door and window frames, plumbing equipment, water supply and drainage piping.
• Electronics: connectors, switches, and other electrical components.
• Mechanical manufacturing: gears, bearings, shaft sleeves, and machined parts.
• Chemical equipment: heat exchangers, pipelines, and reaction vessels.

C22000 offers good processing performance and can be formed by casting, forging, extrusion, turning, and milling. Its work hardening rate is high, so strength and hardness increase significantly after cold working. The alloy resists corrosion well in dry air and performs reliably in seawater and other corrosive environments; however, stress corrosion cracking may occur in environments containing hydrogen sulfide or chlorides.
