Product Introduction

The composition content of H70 brass is between 68.5% and 71.5% copper, with the balance of zinc, while containing trace amounts of lead, phosphorus, iron, antimony, bismuth and other impurity elements. This reasonable composition ratio makes H70 brass has good plasticity and strength, can meet the engraving copper plate for material performance needs.
