42 CASTINGS Mavyari * PIG IRON Mavyari is a natural nickel-chromi- um pig iron and offers a simple, very economical method of making heat- resisting alloy-iron castings for grate- bars and other furnace parts. Cast- ings made with a small percentage of Mayari added to the cupola mixture have much longer life under high- temperature conditions, with but slight increase in cost. Mayari also gives increased wear-resistance and much longer life to machinery parts, such as engine and pump cylinders and piston rings. Further, the use of Mayari results in castings that are free from blow- holes, spongy spots and other imperfections, and that machine easily to a smooth, dense, highly wear-resisting surface even on a thick section. Just ’phone or write to the _ nearest Bethlehem office, and we will be glad to send one of our foundry specialists to dis- cuss the application of Mayari to your uses.
