[China Aluminum Network] aluminum hardness is generally measured with the Webster hardness tester. The national standard GB5237-2004 stipulates that 6063 aluminum profile hardness should be greater than 8HW, and 6061 aluminum profile hardness should be greater than 10HW. China Nonferrous Metals Standard YB/T420-2000 specifies the method for measuring the hardness of aluminum profiles.
The W-20 Vickers Hardness Tester for aluminum profile inspection is a small portable instrument for quick and easy measurement of the hardness of aluminum profiles, pipes and plates. It is especially suitable for the rapid and non-destructive hardness inspection of aluminum profiles at the production site, sales site or construction site. This instrument has passed the performance test of the national technical supervision department and obtained the manufacturing license for measuring instruments. License number: Liao.
The W-20 Vickers Hardness Tester is one of the two types of instruments approved by China Nonferrous Metals Industry Standards YS/T420-2000. The instrument has been applied to most aluminum profile factories and many curtain wall enterprises, aluminum profile use units and projects in China. Quality inspection technical supervision department.
Use 1. Determine whether the aluminum heat treatment, check the heat treatment effect, determine the aluminum profile mechanical properties are qualified.
2. Determine whether the aluminum profile is processed with an inappropriate alloy and determine whether the aluminum profile alloy composition is acceptable.
3. Inconvenience of measurement to the laboratory for long, heavy parts or assemblies.
4. For aluminum production inspection, acceptance inspection and quality supervision and inspection.
Main features 1. Small size, light weight, one-handed operation, easy to carry.
2. Can measure a variety of aluminum profiles.
3. The operation is simple and the operating skills have no effect on the reading.
4. Easy to read, it can be easily converted to other hardness values.
The measuring range is mainly used for measuring aluminium profiles and aluminium alloys, but also copper alloys. Its measurement range is equivalent to:
Aluminum profiles: 24～110HRE
Copper alloy: 60～90HRF
Insulation aluminum profiles With the gentrification of the living environment, new heat insulation aluminum profiles have been exported to foreign countries. Each aluminum profile production company has introduced foreign insulation broken bridge wear strip equipment, and domestic enterprises engaged in aluminum profile processing equipment have also developed thermal insulation broken bridge wear strip equipment. All hope to push the new type of heat insulation aluminum extrusion market. The production cost of insulation aluminum profiles is higher than that of ordinary aluminum profiles, which increases the number of processes such as through-oxidation, spraying, and stripping. Through the connection of broken bridges, silver oxide white material can be connected with color spray paint, sand fabric and coloring material; increase the decorative feeling of aluminum profiles. Five development directions of aluminum profiles. According to the prediction of experts, the aluminum profiles will be Five developments:
1, matte surface aluminum profiles. The matte surface aluminum profile avoids the disadvantages of the bright alloy profile in the architectural decoration under certain environmental conditions to form light pollution, and its surface is delicate and soft, so it is favored by the market. However, the existing matte aluminum profiles have the disadvantage that the surface sand material is uneven and the grain can be seen.
