Long Brass Screw – Shenzhen Shi Shi Tong Screw Factory

Long brass screw is also a long screw. There are two kinds, one is made of copper material, and one is surface treatment is copper plating, this premise is that the material is carbon steel, because carbon steel material plating is not easy to fade, if it is stainless steel, it is suggested to maintain the color, not electroplating.

Let’s start with long screws made of copper material. Copper wire is divided into H70 brass screw wire, imported brass screw wire, and H68 brass screw wire. These screw wires have excellent plasticity (the best in brass) and high strength, good machinability, easy to weld, very stable to general corrosion, but prone to corrosion cracking.It is the most widely used variety of common brass.Copper wire itself is more expensive, so it will be more expensive to make long screws, which is not difficult to understand the reason for the high price of copper screws; To make long screws with copper wire, domestic or less.

Next is the long brass screw made of carbon steel, and then sent to electroplating, long screws copper plated, this plating is also divided into several types, water plating, rolling plating, hanging plating. Which is the most expensive, hanging plating long screw is hanging plating, because rolling plating will make the long screw bending and water plating effect is not so good, so long screw are usually choose handing plating. Also said to the copper will be more expensive, in front of the copper plating is naturally expensive, in general, long brass screw a large part of the reason and surface treatment, the price of itself, the price of long screw and length and combination would be expensive.
