The hinge is made of several materials, such as iron, copper and aluminum alloy. However, with the development of society, hinges made of aluminum alloy gradually replace the iron and copper hinges, mainly because the iron material Although the hinge of high strength, not easy to deformation, can be very good load-bearing, but it is easily corroded by external factors, leading to shorter service life. Copper hinge material performance, but its high cost.
The aluminum alloy hinge surface after its anti-corrosion treatment, corrosion resistance, and its own high hardness and pressure wear-resistant, very suitable for regular switch doors and windows furniture, in addition aluminum plastic good, after the cutting process molding, smooth appearance, color Bright, with a certain degree of decorative, the price is more reasonable.
