1、Advantages and disadvantages of aluminium alloy hinge
advantage:
(1)The casting performance is good. It can be die-casting into precision parts with different complex shapes and thin walls as required, and the casting surface is smooth and smooth. Therefore, we often see many different styles of aluminium alloy hinges, which maximizes people’s personalized customization needs.
(2) It can be used for various surface treatments, such as electroplating, spraying, painting, polishing, grinding, etc. This advantage is mainly to make the hinge have a more colorful appearance, and at the same time, it can also reduce the production cost as much as possible, so that the hinge products can meet each different market.
(3) In the process of melting and die-casting, it does not absorb iron, corrode the molding and adhere to the mold. Therefore, the production of aluminium alloy hinges requires relatively low processing equipment and production environment, which greatly saves production costs.
(4) It has good mechanical properties and wear resistance at room temperature.
(5) Low melting point, melting when the temperature reaches 385 ℃, easy to die cast.
Disadvantages:
(1) Poor corrosion resistance
(2) Poor weather resistance
(3) The surface is easy to bubble, affecting the appearance
