Aluminum alloy door and window material purchase notes A look at aluminum alloy door and window material material. There are six main aspects in the materials used for reference:
1. Thickness: There are 70 series and 90 series aluminum alloy sliding doors. The aluminum alloy sliding door inside the house can use 70 series. The series number indicates the thickness of the door frame thickness in millimeters. Aluminum alloy sliding window has 55 series, 60 series, 70 series, 90 series four. The series selection should be based on the size of the window hole and the local wind pressure value. Aluminum sliding windows used as closed balconies should not be smaller than the 70 series.
2, strength: tensile strength should reach 157 Newton per square meter, yield strength to reach 108 Newton per square millimeter. When you buy, you can use your hands to bend the profile moderately, and you should be able to recover after loosening your hands.
3, color: the same aluminum alloy profile color should be consistent, such as the color difference is obvious, that is not suitable for purchase.
4, flatness: check the surface of aluminum alloy profiles, there should be no depression or bulging.
5, gloss: aluminum alloy doors and windows to avoid the purchase of surface bubbles (white spots) and ash (black spots), as well as cracks, burrs, peeling and other obvious defects in the profile.
6, oxidation degree: The oxide film thickness should reach 10 microns. When you purchase, you can lightly stroke the surface of the profile to see if the oxide film on the surface can be wiped off.

Base Seals are an important component used to seal machines and equipment. They are usually used to prevent liquid or gas leaks and protect machines and equipment from dust, pollutants, and other external elements. Base Seals mainly include rubber seals, oil seals, mechanical seals, O-rings, U-rings, V-rings, X-rings, and other types.
Rubber seals are a type of seal widely used in various machines and equipment. They are usually made of rubber materials and have characteristics such as wear resistance, corrosion resistance, high temperature resistance, and low temperature resistance. Rubber seals are mainly used to seal liquids or gases in machinery and equipment, such as automotive engines, water pumps, pipelines, fans, refrigeration equipment, etc.
Oil seal is a type of seal specifically used to seal lubricating oil. They are usually made of rubber and metal materials and have characteristics such as wear resistance, corrosion resistance, and high temperature resistance. Oil seals are mainly used in equipment such as automotive engines, industrial machinery, water pumps, and hydraulic systems to prevent lubricant leakage.
Mechanical seals are advanced seals used to seal machines and equipment. They are usually made of metal and ceramic materials and have characteristics such as wear resistance, corrosion resistance, high temperature resistance, and low temperature resistance. Mechanical seals are mainly used in high-speed rotating equipment, such as centrifugal pumps, compressors, fans, centrifugal separators, etc.
O-ring is a common sealing element, usually made of rubber material. They have good sealing performance and elasticity, and can be used to seal various liquids and gases. O-ring is mainly used in fields such as automobiles, machinery, and electronic equipment.
A U-shaped ring is a sealing element with a U-shaped cross-section, usually made of rubber material. They have good sealing performance and elasticity, and can be used to seal various liquids and gases. U-rings are mainly used in hydraulic systems, pneumatic systems, automotive braking systems, and other fields.
A V-ring is a sealing element with a V-shaped cross-section, usually made of rubber material. They have good sealing performance and elasticity, and can be used to seal various liquids and gases. V-rings are mainly used in fields such as automobiles, industrial machinery, and hydraulic systems.
7. X-shaped ring
An X-ring is a sealing element with an X-shaped cross-section, usually made of rubber material. They have good sealing performance and elasticity, and can be used to seal various liquids and gases. The X-ring is mainly used in hydraulic systems, pneumatic systems, automotive braking systems, and other fields.
