Tailor Made Lathe Machining Parts In Brass H65 For Electrical And Engineering Applications

Brass H62 Characteristics: Offers good corrosion resistance and is commonly used in hardware, fasteners, and marine applications. Known for its strength and excellent machinability.

Maintenance: Clean regularly with a soft cloth and mild detergent. For corrosion protection, coat with a suitable anti-corrosive agent.

Brass H65 Characteristics: Has higher copper content than other brass alloys, making it more durable and resistant to corrosion. Used in mechanical parts and marine environments.

Maintenance: Prevent tarnishing by wiping with a soft cloth and applying protective coatings when exposed to moisture.

Sandblasting is a process for surface treatment of workpieces. Adopting compressed air as the power, in order to form a high-speed jet beam will spray material (copper ore, quartz sand, emery, iron sand, sea sand) high-speed jet to the surface of the workpiece to be processed, so that the appearance or shape of the surface of the workpiece changes.

Due to the impact and cutting effect of the abrasive on the surface of the workpiece, the surface of the workpiece obtains a certain degree of cleanliness and different roughness, so that the mechanical properties of the surface of the workpiece can be improved, thus improving the fatigue resistance of the workpiece, increasing the adhesion between it and the coating, prolonging the durability of the coating film, and also conducive to the levelling of the coating and decoration.

Cadmium plating is also prone to 'cadmium brittle' phenomenon, usually at higher temperatures, and at the same time the existence of certain stress conditions, can make steel and titanium alloys produce cadmium brittle. As cadmium plating layer in 232 ℃ above can be leached into the steel parts of the matrix, can cause the so-called 'cadmium brittle' phenomenon, so the use of temperature should not exceed 232 ℃.

Cadmium-plated layer can be welded, the plating can reduce the oxidation of copper-plated electrical contacts, but also does not increase the contact resistance. Cadmium-plated layer is usually used in steel fasteners, piping and other stressed parts, aluminium and aluminium alloy parts, magnesium alloy parts, and rubber contact with the steel and copper parts.
