1, light weight, high strength and toughness: density 0.89-0.91g/cm3, only one ninth of steel, copper one-tenth strength of up to 5.0Mpa pressure test above (50kg/cm2) above , toughness, impact resistance.
2, thermal energy: 20 ℃ when the thermal conductivity 0.23-0.24W/mk, than the tube (43-52W/mk), copper (333W/mk), only the second metal tube one per cent with hot water pipe insulation on energy saving effect is excellent.
