ACP 6000

Bar-sawn and double-sided, surface-machined aluminium precision cast plates and cuts.

The main advantages of the precision surface aluminum cast plate ACP 6000 are low inherent internal stress and excellent machining characteristics, in combination with uniform consistency throughout the material. Due to the superior cast structure and extended thermal treatment during production, ACP 6000 offers high dimensional stability during extreme machining. Each plate is covered with protective foil on both sides to ensure surface integrity during shipment.

In many respects the double-sided surface-machined aluminium precision cast plate ACP 6000 is similar to the Mic6 product. However, its guaranteed and outstanding minimal pore characteristic is a distinctive feature. An extremely low material tension also characterizes the ACP 6000. The plate geometry and stability of shape remain unchanged, even at high temperatures. Both sides of all plates are covered with foil to protect their surfaces.

[The aluminum precision cast plate ACP 6000 connects the advantages of Mic6 with the benefits of the aluminum cast plates of the ACP series.]
