High-Precision CNC Machining Parts in Brass H68 for Hydraulic and
Pneumatic Equipment
Product Description:
1.Brass H65Characteristics: Brass H65 has higher copper content than other
brass alloys, making it more durable and resistant to corrosion.
It’s used in mechanical parts and marine environments.
Maintenance: Prevent tarnishing by wiping with a soft cloth and
applying protective coatings when exposed to moisture.
2. Brass H68
Characteristics: Brass H68 offers a good balance of strength and
corrosion resistance, making it suitable for electrical contacts
and fittings.
Maintenance: Keep parts dry and clean. Polishing can help preserve
the material’s luster, and regular inspection for corrosion is
essential.
Applications
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. Especially some elastic
parts, threaded parts, standard parts and aerospace, shipbuilding,
electronics and military products are used to use cadmium plating.
But cadmium vapour and its soluble salts are highly toxic and
seriously pollute the environment. Therefore, the application of
cadmium plating layer is subject to strict limitations, has been
rarely used, most of the zinc plating layer and zinc alloy layer to
replace the cadmium plating layer.
