Aluminum screw

Aluminum screws weigh only about one-third as much as steel screws of the same specification, making them very popular in fields highly sensitive to weight reduction, such s aerospace, racing, and high-end bicycles. Aluminum itself possesses good corrosion resistance, capable of withstanding outdoor or high-humidity environments without additional coatings. Additionally, being non-d possessing excellent thermal and electrical conductivity, aluminum is also frequently used in electronic devices and medical instruments where magnetic sensitivity or heat dissipation is required.
