 Specification: Package include:1Pcs （Need a large amount can contact me, the price can be discounted） Product name: Foam copper Aperture: 0.1mm-10mm (5ppi-30ppi) Porosity: 60%-98% Through hole rate: ≥98% Volume density: 0.1-0.8g/cm3 ppi(number of holes per inch) : 5-130 Tensile strength: 5-18KPa Compressive strength: ≥250KPa Mechanical strength: ≥2-5Mpa High temperature resistance ≤ 600℃ Heat transfer coefficient > 6W/(m2K) Product features: 1) Heat conduction and heat dissipation. Copper foam has good thermal conductivity and can be widely used in motors/electrical appliances and electronic components. 2) Electrical conductivity. Because of its good conductivity, its application in the electrode materials of nickel-zinc batteries and double-layer capacitors is also attracting the attention of the industry. 3) filtration and purification. Copper foam is also an excellent medical filter material and water purification filter material because of its structural characteristics and basically harmless to human body. Application field: (1) electrode material. Due to its good conductivity, copper foam can be widely used as electrode framework material for new batteries such as nickel-zinc batteries and double-layer capacitors. At present, copper foam has been tried by many manufacturers of nickel-zinc batteries and put into mass use. Meanwhile, copper foam is expected to be widely used as electrode collector for double-layer capacitors. In addition, the use of copper foam as electrode material for electrolytic recovery of copper wastewater also has a very broad prospect. (2) catalyst. In many organic chemical reactions, people try to directly use copper foam with large specific surface area instead of punching copper plate as catalyst. Copper foam as a photocatalytic air purification carrier has also been successfully applied. (3) heat-conducting materials. Copper foam has good thermal conductivity, which makes it a flame retardant material with excellent performance. It has been applied in many advanced fire equipment abroad, especially as a flame isolation equipment with excellent effect. In addition, people use the good thermal conductivity and apparent permeability of copper foam, made into the motor, electrical heat dissipation material. (4) noise suppression and shielding materials. Sound wave diffused reflection occurs on the surface of copper foam, and the effect of sound attenuation can be achieved through the principle of expansion and microhole sound attenuation. Copper is an excellent electromagnetic shielding material with similar shielding properties to silver. (5) Filter material. Copper foam products, which have good structural characteristics and are basically harmless to human body, have also been successfully applied as medical filtration materials. At the same time, the application of copper foam in water purification equipment also has a good future. (6) fluid pressure buffer material. The dispersion and buffering effect of copper foam on fluid make it used as a pressure relief protection device of various pressure instruments with excellent effect.
