The Effects of Calcium Chloride Flakes on Aluminum | …
2020/8/18· Calcium chloride flakes, or salt flakes, may come into contact with aluminum if they are used to prevent freezing on or near an aluminum surface. Although these flakes are very useful for preventing dangerous conditions that could be slippery and perilous, they can do some damage to your aluminum surface if you are not diligent.
Corrosion of Aluminum and Aluminum Alloys
• Aluminum alloys have a high strength-to-weight ratio. • Aluminum retains its strength at low temperatures and is often used for cryogenic appliions. • Aluminum has high resistance to corrosion under the majority ofservice conditions, and no colored
