Stainless steel screw anti-corrosion method Stainless steel screws are made of metal, and metal corrosion protection methods are mainly in four aspects, namely the nature of the material, the environment used, the interface between the data and the environment, and the design of the improved metal structure. If a complete corrosion-resistant alloy is used to make the stainless steel screws Unless there is a special need, it is not realistic in terms of economics, or it can completely isolate...
Aluminum alloy fasteners details Aluminum fasteners weigh 1/3 of the weight of their similar steel fasteners. The strength characteristics of such frequently used alloys are surprisingly good. In fact, in terms of strength to mass ratio, aluminum fasteners are higher than fasteners made from any other trade-trade material. Aluminum is not magnetizable. The thermal conductivity of aluminum is very good, about 2/3 of the copper conduction performance of the same volume. Aluminum has good...
The difference between low temperature aluminum hard anodizing and normal temperature anodizing Normal aluminum hard anodized is also called ordinary oxide film thickness is generally 5-15 microns, hardness 200-400HV. Low-temperature oxidation is generally used for hard oxidation, the characteristics of hard oxidation 1: The color film layer is gray, brown, dark green to black, and related to the material composition and process, and the lower the temperature, the thicker and darker the film...

What is a lock washer? Lock washer consists of two washers, the outside is with a radial convex surface, the inner side of the helical surface. The working principle is very simple: when it is assembled, the inner side of the helical tooth surfaces are opposite to each other, and the outer radial convex surfaces are in a state of meshing with the contact surfaces at both ends. When the connecting member is vibrated and the bolt tends to be loosened, only two washers Inside the relative...
Hardware knowledge: stainless steel screw anti-corrosion method Stainless steel screws are made of metal, and the metal corrosion protection methods are mainly in four aspects, namely the material itself, the environment used, the interface between the data and the environment, and the design of the improved metal structure. If a complete anti-corrosion alloy is used to make the stainless steel "target" =_blank>Stainless steel screws, unless there is special demand, it is not realistic in...

CNC help stainless steel screw industry competition development If not developed, the world will stagnate, as will the machine stainless steel screw industry. Nowadays, the development of numerical control technology provides a reliable guarantee for the development of the machine stainless steel screw industry. In other words, the development of the stainless steel screw machine tool industry is inseparable from the CNC technology. Development is an absolute truth. Any high technology cannot...
Stainless steel screw use points The stainless steel screw refers to the shape of a screw made of stainless steel screw wire piercing, and then the thread is licked. Its material is stainless steel. Stainless steel screws are made of stainless steel SUS201 screws, stainless steel SUS304 screws, stainless steel SUS316 screws, etc. In daily life, stainless steel screws are common fasteners. During use, rust is a common phenomenon and it is also a trouble for us. This will not only affect the...

CNC wire cutting aluminum parts common problems and solutions (1) Beds and Columns Beds and columns are basic structures that ensure the mutual position of electrodes and tables and workpieces. The accuracy of the position has a direct influence on the machining. If the accuracy of the machine tool is not high, the machining accuracy is difficult to guarantee. Therefore, not only the structure of the bed and the column should be reasonable, but also have a high rigidity, can withstand the...
The difference between the alkali treatment of aluminum parts and the degreasing of steel parts Alkali corrosion of aluminum parts is very different from that of steel parts. The first is that aluminum itself is not resistant to alkali. For this reason, it is necessary to perform degreasing in a solution of a weakly basic salt or in an organic solution before alkali etching. After the oil on the surface of the workpiece is basically removed, it is carried out in a strong alkali. Flash,...
The advantage of aluminum alloy threaded fasteners Aluminum is a kind of silver-white light metal with good ductility and malleability. It is easily soluble in dilute sulfuric acid, nitric acid, hydrochloric acid, sodium hydroxide and potassium hydroxide solution and is insoluble in water. Aluminum commodities are often made into rods, sheets, foils, powders, ribbons, and filaments. Aluminum can form an oxide film that prevents metal corrosion in humid air. Aluminum powder and aluminum foil can...

It has various specifications and specifications. 1, aluminum alloy reducer quick joint product working pressure: 16Mpa ~ 3.2Mpa. Temperature: -20 to +230°C. 2, aluminum alloy reducer quick joint products work medium: gasoline, heavy oil, kerosene, hydraulic oil, fuel oil, refrigeration...
How to clean and remove aluminum hardware products? The choice of precision aluminum cleaner? Precision aluminum parts generally require cleaning to not corrode the substrate, and can not affect the original bright color of the aluminum. Therefore, ordinary aluminum degreasing or aluminum acid removal and other low-grade aluminum cleaning agents cannot be used. "Aluminolysis" mainly uses acid as a raw material to release a gas by chemical reaction with an aluminum substrate, and gas is...
