Description:

High-purity aluminum particles are also known as aluminum pellets and aluminum sand. Aluminum particles are produced by ultra-high purification processes such as crystallization and solid state, such as sublimation. Bright appearance, cylindrical shape, applied to the surface of aluminum, zinc or thin-walled workpieces. Xinkang New Materials provides customized compositions for commercial and research applications and new patented technologies.

Main chemical composition:

AI≈99.5% Si<0.2% Cn<0.04% Zn<0.04%

Specific weight: 2.7 g/cm3

Hardness: 65-125Hv

Gauge: φ0.6mm-φ2.0mm

Application:

It is widely used in surface finishing of aluminum castings and copper and zinc castings, sandblasting of various metal surfaces, deburring and burr of casting workpieces, sandblasting of blade surfaces, and casting surfaces. It can make your product smooth, clean, shiny, and achieve the effect of whitening. At the same time, aluminum particles can be used in combination with stainless steel sand and stainless steel pellets to achieve a whiter and brighter effect on the surface of the workpiece. Aluminum particles, LED semiconductors, and evaporation coatings are used more, and the purity requirements are also relatively high.
