In the field of CNC machining, the choice of materials directly determines the quality, performance and cost of the product. Whether it is the parts of precision instruments or the product shell in daily life, the right CNC machining materials are the key to realizing the function and value of the product. These materials have their own characteristics and uses. The choice of material depends on the design requirements and use environment of the product. During the design stage, you can choose different materials for machining according to the demands.


Brightstar Precision Prototype machining provides industrial manufacturing with accurate verification and display prototype models for global customers in new product design and development stage. Compared with other companies in the same industry, Brightstar ensures that the most advanced equipment is always used for processing. In terms of cost control, Brightstar can reduce processing costs by 10% - 20% for customers through process optimization and precise procurement, and our prices for the same specification are more attractive.

During CNC machining, aluminum exhibits excellent machinability. The lower hardness makes the cutting process smoother. Good thermal and electrical conductivity opens up a broad space for it in the electrical and electronic fields. In addition, aluminum has a very high recycling value, which is in line with the current concept of environmental protection and sustainable development.
