Product catalog summary
Specifications:
Phosphorous deoxidised copper (DHP-Copper) is specified with a width range up to 1100 mm, thickness range from 0.4 to 1.5 mm, coil weight up to 4000 kg, and sheet length up to 6000 mm.
Fabrication Properties:
The material exhibits excellent formability, soldering, and brazing capabilities. TIG and MIG welding are rated as good, while EBW is poor. It is crucial to remove the oxide layer before welding, soldering, and brazing.
Chemical Composition:
Copper (Cu) content is a minimum of 99.90%, and Phosphorus (P) ranges from 0.015 to 0.040%.
Physical Properties:
Density is 8.94 kg/dm3. Thermal expansion is 17*10-6 1/K, specific heat is 385 J/kg K, and thermal conductivity is 335 %W/Cm.
Typical Use:
Commonly used in architecture for roofing, facades, window and door frames, and decoration.
Material Designation:
Cu-DHP, CuZn0.5, CW024A, CW119C, R220, H040, R240, H065, R290, H090, CuSn0.15 CW117C, R250, H060, R300, H085, CuAl5Zn5Sn1 CW309G R400, H080, CuSn4 CW450K R290, H070, CuZn15 CW502L R310, H090.
Mechanical Properties:
The material meets the requirements of standard EN 1172. Tensile strength ranges from 220 to 400 N/mm2, 0.2% proof strength ranges from 140 to 290 N/mm2, hardness ranges from 40 to 115 HV, and elongation ranges from 4% to 45%.
