A process called precipitation hardening reduces the malleability of an aluminum alloy. The material is heated to a temperature below the melting point. This increases the amount of the impurity that will dissolve in aluminum. The alloy is allowed to cool at a particular rate and allowed to age...
Sulfides improve the alloy’s ability to form chips that break away cleanly from the cutting tool during the machining process. Unless the part is properly passivated, sulfides can act as initiation sites for corrosion on the surface of the fabricated product. In both cases, passivation is ...
As with other soldering irons, it melts solder -- an alloy that softens at a low temperature and hardens as it cools. Although solder (pronounced "soder") is commonly used to connect electronic components, you can also use it to make jewelry and stained glass. With the right type of ...
An age-hardenable copper alloy made of 1.2 to 2.7% cobalt, which is able to be partially replaced by nickel, 0.3 to 0.7% beryllium, 0.01 to 0.5% zirconium, optionally 0.005 to 0.1% magnesium and/or iron and in some instances up to a maxi... T Helmenkamp,D Rode - US 被引量: 135...
As the thermally sprayed metal, self-fluxing alloy is desirably used, and, as the metallic film, nickel series and cobalt series magnetic metals are preferably used. Next, while a temp. gradient of 5 to 30°C/mm is formed between the face to be thermally sprayed in the base material 1...
Nichrome wire is an alloy of two metals, nickel and chromium. This alloy is used in heating elements in a number of household products, from curling irons to toasters. Nichrome wire has two features that make it a good producer of heat: It's a poor conductor of electricity compared to ...
The Neodymium, Iron and Boron are measured and put in a vacuum induction furnace to form an alloy. Other elements are added, as required, for specific grades, e.g. Cobalt, Copper, Gadolinium and Dysprosium (e.g. to assist with corrosion resistance). The mixture is melted due to the ...
For the handle, it could be changed to Zinc alloy and aluminum handle Package details: Each valve by one polybag, inner box, Cartons with wooden pallets Application: House connection and drinking meter networks, water pipe connection and flow control ...
The process of soldering involves heating the point at which two electronic components are supposed to be joined. Localized heating of the joint allows solder to form an intermetallic alloy between copper and solder, which provides both mechanical strength and electrical conductivity. We explain this ...
