5A83 Aluminum Cast Plate

CHAL 5A83 aluminum cast plate, also known as aluminum cast tooling plate, aluminum cast mold plate, and cast aluminum tool & jig plate, is an improved aluminum alloy plate of 5083, which was developed exclusively by CHAL and introduced in 2012. CHAL 5A83 aluminum cast plate is a vertical cast, stress-relieved, extraordinarily dense, dimension stable, high strength(without heat treatment) machined plate providing sound dimensional stability with minimal or no distortion even after extensive machining operations.

CHAL 5A83 Aluminum Cast Plate

CHAL 5A83 aluminum cast plates have precision machined surfaces for superior flatness, flat within 0.3mm, and +/- 0.1mm thickness tolerance, and are protected with PVC plastic on two sides. Cast aluminum plate typically has a surface roughness of 0.4µm Ra or better. CHAL 5083 aluminium cast plate has a tensile strength of 41KSI, a Hardness of 70HB, and a Yield Strength of 18 KSI.

CHAL aluminum cast plate has outstanding machinability and responds very well in today’s high-speed cutting environments. It is the preferred choice for engineers that require a dimensionally stable product that has a great strength-to-weight ratio. The cast plate is designed especially for the growing high-temp plastic and mold & tool industries.

The Reasons for Choosing 5A83 Aluminum Cast Plate as Mold & Tool & Jig Material

The CHAL 5A83 aluminum cast plate is more cost-effective than the wrought aluminum plate and tool steel.
Aluminum cast plate lowers real-time production costs through machinability advantages.
Compared with aluminum mold/ tool plate, tool steels are too hard.
Compared with cast 5A83 aluminum cast plate, wrought alloys are too soft and gummy.
Compared with rolled plate, CHAL 5A83 precision-milled aluminum cast plate has a finer and more homogeneous grain structure, with a specific state of stress-relieving, which makes there is almost no deformation after the high speed of machining and cutting. However, the rolled plate has a directional structure, striped grain distributes along the processing direction. They’re always showing some deformations after machining.
Steels and wrought alloys increase tool costs and machine time, except for the CHAL 5A83 aluminum cast plate.
CHAL 5A83 aluminum plate has exceptional corrosion resistance properties and weldability.
