Aluminum CNC Machining

Aluminum is a very commonly used metal material in CNC machining. Due to its low density, high strength and hardness, as well as strong heat resistance, corrosion resistance, and good electrical conductivity, it is favored by many industries. In particular, aluminum materials such as 6061-T651, 7075-T651, and 2024-T351 are especially popular in the aerospace, medical, and automotive industries because they offer a good balance of performance and very low cost. We are an aluminum CNC machining manufacturer from China with more than 10 years of experience in this industry. With our advanced CNC machining technology, we are able to help you produce aluminum parts with very tight tolerances.

We provide comprehensive aluminum alloy parts manufacturing capabilities centered around CNC milling and turning, covering multi-axis machining and turn-mill compound machining. Relying on intelligent production management and supply chain networks, we ensure efficient and cost-effective fulfillment of needs from rapid prototyping to small and medium-volume production.
