Very grateful to xiaokaikaiya, AAA forgot to hide 8, 100 plate _ business; the origin of this issue I elaborate: late this year I ride a motorcycle to go to China, Sichuan, Tibet, the new line, two cars and equipment a total of about 900 I will be equipped with two side boxes and a trunk, the three boxes are 7075 material, a single box with stents are about 8 kg, three boxes a total of about 24 kg, due to The vehicle carrying equipment is too heavy lead to tire wear serious, more than 14,000 km new tire completely worn out, so I want to use the new material to re-create the side box, on the one hand to reduce the weight, but the material strength can not be reduced, because the motorcycle reversing When the side box can be used with the front bumper to form an effective protective space, the protection of the human leg and vehicle protection is very significant! The
??? Do not know whether the above statement is clear, there are problems you can contact.
I simply said that you can use light steel keel. Hundred bai strong have this ah
Recommend 7050 and 7055,
Part of the Al-Li alloy can also, 8 series, but the price is almost 2 times.
7075 should be the most suitable aluminum alloy sheet material on the market, and look at the magnesium alloy sheet? , The specific strength of magnesium alloy slightly stronger, it is recommended that you still make some improvements in the structure of it, the thick place thick, the thin place thin, the other two side box and the back box under the reasonable allocation of it, for the back box Put some light things, so the weight is more balanced.
7075 aluminum alloy is Al-Zn-Mg-Cu super-hard aluminum, 7075 alloy is the late 1940s has been used in the aircraft manufacturing industry, is still widely used in the aviation industry, ultra-high strength deformation of aluminum alloy. It is characterized by good plasticity after solution treatment, good heat treatment strengthening effect, high strength below 150 ℃, and particularly good low temperature strength; poor welding performance; stress corrosion cracking tendency; need to be covered by aluminum or other Protection processing use. Two - stage aging can improve the ability of alloy to resist stress corrosion cracking. In the annealing and quenching state of the plastic slightly lower than the same state of 2A12. Slightly better than 7A04, sheet static fatigue. Notch sensitive, stress corrosion performance is better than 7A04, of which 7075T651 state is particularly top grade, known as aluminum The best products, high strength, far better than soft steel. This alloy has good mechanical properties and anodic reaction, is a typical aerospace aluminum alloy material.
