Product Description
Aluminum tubing is a hollow metal pipe made from pure aluminum or aluminum alloys through extrusion, classified as a type of nonferrous metal pipe. Its product forms include square tubes, round tubes, and patterned tubes; based on manufacturing method, it is divided into seamless aluminum tubes and conventional extruded tubes; and according to precision requirements, it is further categorized into standard-grade tubes and precision-grade tubes that require secondary processing. It is primarily used in industries such as automotive, aerospace, electrical appliances, agriculture, and home furnishings.
This material is lightweight and corrosion-resistant, with its strength further enhanced through heat treatment; however, its corrosion resistance must be improved via anodizing, electrophoretic coating, or aluminum cladding. It exhibits excellent bendability for easy installation and offers energy-saving benefits in refrigeration systems due to its corrosion-resistant inner surface and low thermal resistance. Manufacturing processes include chemical polishing and mechanical brushing, with nylon guide lubrication sleeves employed during cold drawing to prevent damage to the inner wall. Aluminum coil tubing, featuring a continuous structural design that minimizes joints, enables innovative applications in hydrogen storage and transportation. Supporting processing equipment includes automated clamping devices that utilize reverse threads for precise gripping.
