GGG-40/15

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

features

In GGG-40/15 its structure is ferritic with low hardness (190 HB max.) Good machinability and surface finish Offers good electrical conductivity and good magnetic permeability. Good noise absorption and vibration damping This quality offers a high percentage of elongation. Obtained by ferritizing annealing of GGG-50 quality.

Brinell hardness

120-190 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 nodular (spheroidal) graphite type V & VI according to ISO 945. The periphery zone contains approximately 200/250 nodules / mm2 and is predominantly ferritic (> 90 %), with a nucleus containing 90/150 nodules / mm2. The core matrix is ferritic with a 10% perlite. Cold carbides will be less than 5 %, very dispersed.
