3. Resistance to acceleration of corrosion
3.1. Comparison of corrosion resistance properties between Type 2 and W.R.Alstar:
Photo-2 shows results of salt spray tests (testing conditions; 5% NaCl, 35ºC) conducted on Type 2 (pure aluminum type) and W.R.Alstar (Al-Si alloy type) with different compositions of the coating baths to check their respective resistance to acceleration of corrosion. The results show no significant difference attributed to different compositions of the coating baths.
