Description：
H68 ordinary brass has excellent plasticity and high strength, good machinability, and is easy to weld, It has extremely good plasticity (the best among brass) and high strength, good machinability, easy welding, and is very stable to general corrosion. However, it is prone to corrosion cracking in an ammonia atmosphere. H68 is the most widely used variety in brass.
Applications:
1.Electronic: electrical connectors, terminals, springs
2. Architectural decoration ：Building piping, fittings, and decorations
3. Mechanical manufacturing :transmission components, sliding components
4.Automotive components: Engine components、Connecting components、 fuel system components
5.Medical equipment: surgical instruments, dental instruments
6. Building piping, fittings, and decorations
