The role of one element in the alloy

Among the alloy components, effective alloying elements: aluminum, copper, magnesium; harmful impurity elements: lead, cadmium, tin, iron. (1) Aluminum effect: 1 Improve the casting properties of the alloy, increase the fluidity of the alloy, refine the grains, cause solid solution strengthening, and improve mechanical properties. 2 Reduce the ability of zinc to react with iron […]


Zinc alloy select

Which zinc alloy to choose, mainly considering three aspects The use of the die casting itself requires the performance requirements to be met. include: (1) Mechanical properties, tensile strength, is the maximum resistance when the material breaks; Elongation is a measure of material brittleness and plasticity; Hardness is the resistance of the surface of the […]


Several important zinc alloys

Different zinc alloys have different physical and mechanical properties, which provides a choice for die casting design. According to the manufacturing process, zinc alloy can be divided into two types: cast zinc alloy and deformed zinc alloy. The yield of cast alloys is much greater than that of deformed alloys. The composition, properties and uses […]


Alloy Handle

Commonly used in zinc alloy handles. Alloy handles are materials with metallic properties synthesized by two or more metals and non-metals by certain methods. Generally obtained by melting a homogeneous liquid and solidifying. According to the number of constituent elements, it can be divided into binary alloys, ternary alloys and multicomponent alloys. China is one […]


Luxury handle lock

It is eye-catching or hidden. In the use of functional furniture, the handle should be hidden, so as not to interfere with the owner’s use, the handle of the food decoration cabinet can be adapted to its own eye-catching style, choose a pair of gloss and contrast with furniture color Head handle. (1) The entrance […]


Handle Common specifications

Common specifications 1: single hole; 2: There are two holes: all are the center hole distance: 32mm 64mm 76mm 96mm 128mm 160mm 192mm 224mm 256mm 288mm 320mm 480mm These specifications are the most common. Some can also be customized according to the size of the door.


Handle Classification

According to the material: zinc alloy handle, copper handle, iron handle, aluminum handle, bakelite handle, log handle, ceramic handle, plastic handle, crystal handle, stainless steel handle, acrylic handle, marble handle and so on. 1 according to the material: single metal, alloy, plastic, ceramic, glass, etc.; 2 according to the shape: tube shape, strip shape, spherical […]


Handle Surface treatment

There are many ways to handle the surface of the handle. Different handles have different surface treatment methods. The surface treatment of stainless steel has mirror polishing and surface drawing. The surface treatment of zinc alloy is generally galvanized (white plated, Zinc plating), bright chrome plating, pearl chrome plating, matt chrome, black enamel, black lacquer, […]


Handle Material

There are many kinds of materials for handles, such as raw wood (redwood), but mainly stainless steel, zinc alloy and iron and aluminum alloy. The industrial handle materials are mainly stainless steel and zinc alloy, aluminum alloy, nylon, etc. Due to the high requirements of industrial handles in terms of performance and use environment, the […]



Handle refers to the device that pulls or manipulates (opens, closes, hangs) (such as round handle rope, cable, handle). Such as: plastic window canopy handle. The handle is a component for easy opening and closing of the door on the door body. The form and function of the handle in the industrial box are very […]
