Use of aluminum particles:
Surface finishing processing is widely used in aluminum casting and copper, zinc casting, metal surface polishing, sandblasting burr, burr removing casting workpiece, blade surface, casting products surface sandblast etc.. It can make your product smooth, bright, bright and whitening.
At the same time, but also the use of stainless steel and aluminum powder sand, stainless steel pill mix, on the surface of the workpiece to achieve whiter brighter effect.
Aluminum particles, LED semiconductors, and steaming are used more, and the requirements for purity are also higher.
The main chemical composition of aluminum particles:
AI = 99.5% Si<0.2% Cn<0.04% Zn<0.04%
Specific gravity: 2.7 g/cm3
Specification: [Phi] 0.6mm- [Phi] 2.0mm
Pure aluminum targets (99.99%, 99.995%, 99.999%, 99.9995%, 99.9999%)
Al Si alloy targets (99.99%, 99.995%, 99.999%, 99.9995%, 99.9999%)

Grain size distribution
Usually, the target material is polycrystalline structure, and the grain size can be from micron to millimeter. The sputtering rate of the same component target and the fine size grain target is faster than that of the coarse grain. However, the thickness distribution of the deposited film is also more uniform than that of the target with smaller grain size. The target of manufacturing vacuum melting method can ensure the bulk no pores exist, but the target made by powder metallurgy, it is likely to contain a certain number of stomata. The existence of the pores will lead to abnormal discharge when sputtering, and the impurity particles are produced. In addition, when the target is moved, transported, installed and operated, the target is easily broken because of its low density.
