Characteristics:
The products made by vacuum casting have copper purity and good thermal conductivity. There are hardly any defects such as gas hole, blowhole, loose in the castings.
With reliable welding technology of cooper and steel, the welding seam could be adapted to high temperature and high strength working congitions.
After optimal designing of the inside structure of the water passage, the products have smaller water resistence and good cooling effect.
Tachnical parameter:
Chemical Composition: Cu≥99.93% O≤30ppm H≤1.0ppm
Electric conductivity: σ≥90%IACS
Welding Seam X-ray Detection: according to GB3323-87 l-ll standard.
