Wieland-SB7 is a nickel-containing special brass with hard, wear resistant manganese silicides. It has been specially developed for the function of the freely running slipper shoe. Its high 0.2% proof stress makes it particularly ductile and allows it to be easily bent around the joint of the steel piston. Wieland-SB7 can also be used for other antifriction elements.
