Abstract
Content
A new high strength aluminium alloy intended for tubes in automotive radiators has been developed. The material is an age hardening alloy containing Mg, Si, Cu, and Mn. Titanium is added for corrosion protection.
The post-braze strength of the material is dependent on the cooling rate after brazing. With 1°C/s cooling rate between 400 and 200°C, the Rp0.2 will be about 75 MPa.
The corrosion resistance of the material is excellent. It is more noble than standard fin materials and will be protected by sacrificial action. Any attack in the material will be forced into a lamellar mode due to the Ti addition.
