Some knowledge about bearings
Aluminum bronze can be used to produce bearing related products. [Standard bearing]: The inner diameter or outer diameter, width (height) and size of the standard bearing conform to the bearing shape specified in GB/T 273.1-2003, GB/T 273.2-1998, GB/T 273.3-1999 or other relevant standards size. ...Read more -
Effects of Oxidative Coloring of Brass Rods
Brass rods are easily oxidized when exposed to the air for a long time, so is there any good measure to prevent the oxidation of brass rods? 1 Pair of brass rods are sealed and packaged, and two bags of desiccant are added at the same time. 2 The wooden shaft and the wooden box board are dried. 3...Read more -
Oxidation reasons and treatment methods of copper rods
The important factor affecting the surface quality of purple copper rods is the production process, and is closely related to all production processes. The reasons for the oxidation of red copper rods are as follows: 1. The pre-drying time of the insert is too long. 2. The acid corrodes the coppe...Read more -
What is the main purpose of white copper? How can it be distinguished from silver?
We use a lot of metals in our lives, and there are metals in various products. White copper is a copper-based alloy with nickel as the main added element. It is silver-white and has metallic luster, so it is named cupronickel. Copper and nickel can be infinitely dissolved in each other, thus form...Read more -
How to Smelt Simple Brass
Raw material selection The raw material taste should improve with the taste of brass varieties. When smelting non-essential brass, if the quality of the charge is reliable, sometimes the use of old material can reach 100%. However, in order to ensure the quality of the melt and reduce the burning...Read more -
What is the difference in performance between tin bronze and beryllium bronze?
Tin bronze is actually a metal material with tin as the main alloying element, and its tin content is generally between 3-14%. This material is mainly used to make elastic components and wear-resistant parts, deformed tin bronze The content of tin does not exceed 8%, and sometimes lead, phosphoru...Read more -
Heat Treatment Process of Tin Bronze Contacts
Some switchgear contact parts are made of tin bronze material, which requires good elasticity, wear resistance, anti-magnetic and corrosion resistance. Due to the complex shape of the part, in the process of stamping and bending, in order to make the workpiece have sufficient toughness while main...Read more -
Copper alloy corrosion
Copper alloys have excellent resistance to atmospheric and seawater corrosion, such as silicon bronze, aluminum bronze and so on. In general media, it is dominated by uniform corrosion. There is strong stress corrosion susceptibility in the solution in the presence of ammonia, and there are also ...Read more -
What are the factors that cause copper alloy corrosion
Copper alloy corrosion atmospheric corrosion The atmospheric corrosion of metal materials mainly depends on the water vapor in the atmosphere and the water film on the surface of the material. The relative humidity of the atmosphere when the corrosion rate of the metal atmosphere begins to increa...Read more -
Smelting properties of tin bronze
The most harmful impurities in tin bronze are aluminum, silicon and magnesium. When their content exceeds 0.005%, the resulting SiO2, MgO and Al2O3 oxide inclusions will contaminate the melt and reduce the performance of some aspects of the alloy. When smelting tin bronze, since the boiling point...Read more -
