Aluminum Block for Machining Milling
Aluminum block is widely used in precision machining, mold manufacturing, aerospace structures, and industrial equipment due to their excellent strength-to-weight ratio, machinability, and corrosion resistance.
At Shenzhen Chinalcometal, we supply a full range of aluminum blocks in multiple alloys including 6061, 7075, 2024 and marine grade 5083, available in large stock sizes or precision cut-to-size according to your requirements. Whether you need standard blocks or near-net-size materials for CNC machining, we provide reliable quality and fast delivery.
Aluminum block typically refer to thick, solid aluminum materials that are larger and heavier than standard plates. They are commonly used as raw material for machining or as structural components in demanding applications.
Compared with aluminum plates, blocks offer greater thickness and improved stability, making them ideal for high-precision machining and load-bearing applications.
