GG-20

Available formats: Sheet metal, plates, bars, profiles and wires.

features

GG-20 is the degree of lowest hardness of qualities. This material offers exceptional machinability and excellent surface finish, but with limited wear resistance and resilience. Noise, vibration damping and thermal conductivity are excellent in this degree. Complies with EN 16482: 2014 | IN GJL-200C.

Brinell hardness

120-200 HB test with 10 mm diameter ball and 3000Kg load. depending on the size of the section. Hardness readings are taken throughout the entire section of the bar. The hardness values for rectangles depend on the relationship between height and width and can be supplied upon request.

Micro structure

It contains graphite 'A' type sheets, in accordance with ISO 945. The periphery zone contains 'D' type sheets and 'E' interdendritic graphite. The structure of the matrix, in nucleus, is mostly ferritic with less than 10 % of perlite in total.
