Alpha Shredding Group is a factory in New Jersey, USA, that specializes in recycling scrap cars and old metals. It has four recycling centers, and the main machines it uses are metal crushers produced by Danieli.
Alpha Shredding Group has tried hammers of various materials from many factories, including high manganese steel, alloy steel, and ceramic inlays, but they have not achieved good results.
Starting from October 2023, Qiming Casting will begin to supply DH alloy hammers with dual hardness. After a trial period, we visited the customer and the customer was very satisfied with our product.
