Product Description

Performance

Aluminum is a silver-gray metal with a relative mass of 26.98, a relative density of 2.55, a purity of 99.5%, an aluminum melting point of 685 degrees, a boiling point of 2065 degrees, and a melting endotherm of 323 kj/g. Aluminum is reductive and highly oxidizable during oxidation. Exothermic. During rapid oxidation, the heat release is 15.5 kj/g per gram. Aluminum is a ductile metal and easy to process. The oxide film on the surface of the metal aluminum is transparent and has good chemical stability.

Application

An efficient catalyst: nano-aluminum powder added to the solid fuel rocket, greatly improve the speed of fuel combustion to improve combustion stability;

Activated sintering additives: AlN powder mixed with 5 to 10% nano-aluminum body to reduce the sintering temperature, sintered density and thermal conductivity; nano-aluminum integrated components of the substrate, the thermal conductivity about 10 times, can be solve the integrated components of integration.

Conductive surface coating of the three metals and scrap metal processing: nano-aluminum activated surface temperature below the powder melting point coating, under anaerobic conditions, this technique can be applied to the production of microelectronic devices.

Four widely used high-grade metal paint, composite materials (thermal spraying composite metal powder, ceramic composite steel pipe) military (filler), chemical (various catalysts, pesticides), metallurgy (aluminum thermal metallurgy steelmaking Deoxidizer), shipbuilding (conductive coating), refractory materials (steel-making furnaces, magnesia carbon bricks), new building materials (aerated concrete made gas agents), anti-corrosion materials, fireworks, and so on.
