Recently, the technical team of Hunan Qianlong New Materials Co., Ltd. has successfully obtained a utility model patent authorized by the State Intellectual Property Office and obtained a patent certificate.

       The products produced by the company's short-process preparation technology of large roll weight (ultra-long scale) aluminum alloy materials have the characteristics of large single piece weight (ton-level disc material), completely no joints, uniform head and tail structure and performance, and no extrusion coarse grains. Rings, no central cracks, rich product specifications and states, etc.

       The company's products cover 1XXX-8XXX series aluminum alloy series: including aluminum alloy rods (φ8-30mm) coiled materials, coiled wires (φ1-8mm), (φ30mm) or above bars, hexagonal bars, flat wires, and thin aluminum strips , high-strength and high-conductivity aluminum rows, finely drawn rods and other aluminum alloy precision processing products. 

       The company's products are mainly used in high-end equipment manufacturing fields such as aviation, rail transit, automobiles, and 3C intelligence. Products include: high-strength and high-conductivity aluminum alloy materials for subways, light rails, and maglevs; forged materials for automobiles, engineering machinery, and aerospace; connecting materials such as rivets, screws, and welding wires for aerospace and transportation equipment manufacturing; aluminum for new generation 3C smart equipment Alloy materials, etc.
