H68 brass tube is one of the most widely used varieties of ordinary brass. It has good plasticity and high strength, good machinability, easy to weld, and is stable to general corrosion, but is prone to corrosion cracks. The performance of H68 brass tube is very similar to H70, but it has a tendency to "season crack" during cold working and is used for complex cold drawn and deep drawn parts, such as corrugated pipes.
