Aluminium seamless tubing is a top-notch, lightweight option crafted through an extrusion process that creates a consistent structure without any welded seams. Companies like Bosega Pipes & Tubes in Cape Town, South Africa, supply this tubing, which is prized for its impressive strength-to-weight ratio, smooth inner surface, and outstanding resistance to corrosion. The seamless design boosts pressure resistance and reliability, making it perfect for high-performance uses in aerospace, automotive, marine, and industrial systems where precision, durability, and low weight are crucial.
Typically, aluminium seamless tubing is made from alloys like 6061, 6063, 6082, and 7075, which include aluminium along with controlled amounts of magnesium, silicon, manganese, and zinc to improve mechanical strength and corrosion resistance. Depending on the specific alloy and temper, these tubes can show tensile strengths from 150 to 570 MPa and yield strengths between 100 and 500 MPa. The seamless manufacturing process guarantees a uniform grain structure, excellent dimensional accuracy, and reliable mechanical performance even under varying pressure and temperature conditions.
