waterstops with high corrosion temperature resistance

Aluminum alloys with improved high temperature

Several aluminum alloys with differing nickel/iron ratios underwent less corrosion at 350 than at 260 C From the results of a study of their behavior within this temperature range the composition Al-1 w/o Ni-0 5 w/o Fe-0 1 w/o Ti (A288) was chosen for further investigation The temperature at which improved corrosion behavior of this alloy was obtained depended on its silicon content

High Temperature resistance materials

High-temperature resistance metals are also known as refractory metals These metals are much harder at room temperature and usually have a melting point of above 2000 degree Celsius The term 'refractory' is used for these materials in specific fields including
