Overview

ZCuAl9Fe4Ni4Mn2 cast aluminum bronze refers to plates and strips with a thickness of less than 0.1m, all of which are rolled copper foils (rolled copper foils), excluding electrolytic copper foils. The commonly used foil products include pure copper foil, brass foil, bronze foil, and white copper foil. The size range of foil material is 0.05-0.1mm (thickness) #215; 40-600mm (width), supplied in rolls, with a length generally not less than 5000mm. Its state is divided into soft (M) and hard (Y). Copper alloy foil products are mostly in a hard state, and pure copper products with a thickness of no more than 0.02mm are generally also in a hard state. Copper alloy tube rod

The annealing furnace for treating leakage points in ZCuAl9Fe4Ni4Mn2 cast aluminum bronze is always in operation. For some leakage points, temporary treatment such as applying high-temperature sealant can be taken, and bottom treatment should be done when there is an opportunity to shut down the furnace. Repair welding on the cracked area; Old or damaged gaskets and rings need to be replaced; Replace components with vulnerabilities, such as sections, etc; Tighten loose bolts; Apply high-temperature sealant. In the inspection of the airtightness of the annealing furnace, the key points of leakage inspection should be determined, the correct inspection tools should be used, and proper handling should be carried out in order to ensure the airtightness of the furnace, effectively produce high surface galvanized products inside the furnace. Most molds are made of alloy steel and high-speed steel, while carbon steel is increasingly being used. The microstructure of alloy steel after quenching is mainly twinned, with some microcracks, and high carbon needle like or sheet-like martensite. The higher the carbon content and alloy content, the inevitable presence of carbides in the form of shapes, bands, and chains in the steel, which often lead to brittle fracture or early failure of the mold during use.

Density, as a property of steel, is closely related to its composition and affects the range and mode of use of the material; Related to specifications, it affects the price.
