Properties
1. Low density with good weldability
2. Heat resistance
3. Good corrosion resistance, resistant to strong acids and strong base
4. Non-toxic, suitable for food hygiene requirements, can be used for food utensils
5. Easy to accumulate static electricity
6. Easy to age with copper contact
7. Poor weather resistance, sensitive to ultraviolet light, easy to age
8. Poor cold resistance, low low temperature impact strength
Application
Suitable for making general mechanical parts, corrosion resistant and insulating parts, drinking water or sewage pipe, spraying carrier, corrosion resistant trough, acid and alkali resistant industry, waste water, exhaust gas discharge equipment, food machinery, chopping board, rolling pin, plating equipment and etc.
