Many countries are producing the alloy, is the largest amount of hard aluminum. The alloy is characterized by: high strength, a certain degree of heat resistance, can be used as 150 ° C below the working parts. Temperatures above 125 ° C, the strength of the alloy 2024 is higher than the 7075 alloy. Hot state, annealing and quenching states are better formability, heat treatment significantly enhanced the effect, but the heat treatment process demanding. Corrosion resistance is poor, but coated with aluminum can be effectively protected; easy to crack welding, but using a special welding process can also be riveted. 2024 Aluminum Usage: nails, card wheel hub, propeller components and various other structures. The company's complete product specifications, and the price is reasonable, but also according to the different needs of users, can be non-standard build. Welcome new and old customers call to discuss the order or online! Ad effective long-term, so the price is only online reference price, current price due to the specific specifications, styles, models, prices, depending on the material details, please call or contact Want!
