Sumitomo Alzinc (hot dipped 55 % Al-Zn alloy steel sheet; referred to below as AZ, Alzinc or Alzinc sheets) has corrosion resistance and durability three to five times that of galvanized sheet, making it a suitable material for roofing, walls etc. in harsh environments. Demand for this surface treated steel sheet has been increasing steadily in recent years. In the automotive industry, however, Alzinc is still not widely used in Japan, although it is becoming more widely used overseas. Typical applications are the exhaust system and the circulation system. Alzinc is expected to find increasing applications in vehicle bodies and interiors, either as an alternative to painted parts or in vehicle exhaust system, where its high heat resistance usable maximum temperature: 400 deg C) is an advantage. This paper reports on the properties like sheared edge corrosion resistance, corrosion resistance of hemmed model, high temperature corrosion resistance after spot welding, discoloration by heating, and spot weldability of Alzinc in automotive applications.
