About brass H62:
Brass H62 refers to a common brass with an average copper content of 62%, featuring good mechanical properties, good plasticity in the thermal state and enough plasticity in a cold state, good cutability, ease of soldering and welding, and corrosion resistance but the tendency of corrosion failure.
Brass H62 is a common brass variety with wide application due to low prices. H62 (brass 46) is much harder in phase β than in phase α at room temperature and thus can be used for the parts that take larger loads. Thermal machining can be performed for the dual-phase brass at over 600 ℃.
The microscopic structure of the α+β dual phase brass: α is the gloss white solid solution and β is the CuZn-based order solid solution. A Highfield has an inhibiting effect on the hollows during the H62 brass deformation at high temperatures.
Purpose of brass H62
Brass H62 can be used to manufacture loaded parts by various types of deep drawing and buckling, such as dowels, rivets, gaskets, nuts, conduits, barometer springs, screens, and radiators.
As a professional custom precision CNC turning and CNC milling services supplier, Yijin Hardware has special research on brass H62 machining and rich machining experience and is capable of meeting all requirements of every customer for precision brass machining in a perfect way.
About electroplated decorative chromium
Chromium is a metal of silver color with a slight blue luster. The chromium coating has very high hardness, which is higher than that of the hardest quenched steel and only second to that of diamonds, and high abrasion resistance.
The chromium coating also has good thermal resistance, and its hardness or color does not have obvious change as long as the temperature is below 500 ℃.
Chrome plating on the surface polished in advance can lead to a silver-blue coating with a specular gloss. Chromium has a very high passivation property.
A very thin passivation coating is easily produced on a workpiece’s surface and does not change in moist air, retaining its glossy appearance for a long time. Besides brightness and beauty, the passivation coating presents a precious metal-like appearance which is good for decoration.
Purpose of electroplated decorative chromium
Since the chromium coating has a lot of outstanding performances, the chrome plating technology is widely used. For example, decorative chrome plating can be used to produce decorative coatings for protective coatings.
Decorative chrome plating is required for the exposed parts of a lot of things such as trains, cars, bicycles, medical devices, light industrial products and metal furniture. Because of good glossiness and high light reflection, decorative chrome plating is often performed for retroreflector surfaces.
The chromium coating features good hardness and abrasion resistance, so technologies including hard chromium plating, spongy chromium plating, milky white chromium plating and duplex chromium plating are widely used for the machining processes of various parts, such as shafts, cutting tools, engine cylinders, piston rings, measuring instruments and blades.
Machining Difficulties and Solutions of Custom Precision CNC Turning for Chrome-Plated Brass Parts
Brass tends to deform during CNC turning, so sharp cutters that are made in Germany should be selected. Yijin Hardware only uses the milling cutters and turning cutters made by well-known German companies, so as to guarantee not only the machining accuracy but also the surface finish.
In addition, during CNC turning, both the feed speed and the feed amount need attention. Because brass is kind of soft and possibly damaged by bumping, after machining, the operator must clamp or remove the brass parts with care, so as to avoid scratches or bruises.
Otherwise, bumpy surfaces will occur after subsequent chrome plating for surface treatment, leading to rough and untidy parts. With a history of over 20 years in the brass machining field, Yijin Hardware has rich practical experience and technical merits in terms of both cutter selection and operating technicians.
As far as chromium electroplating is concerned, Yijin Hardware has its own surface treatment factory to handle surface treatment quality problems in a good way, avoiding surface treatment defects caused by second-time shipping. Yijin Hardware combines quality CNC machining processes with excellent machining knowledge and reasonable prices.
