Why are aluminum parts cleaned with nitric acid and hydrofluoric acid?

The aluminum parts processing industry has been to clean oil removal mainly by acid cleaning, using acid reaction to remove the surface of aluminum oil, but also to remove the raw edge of the product, so that the product surface oxidized to white. However, the high precision requirements of aluminum products should not use acid aluminum products cleaning agent. In addition to the oil to be completely removed at the same time can not have any impact on the surface of the product, do not change the color, size.

What are the features of marine grade aluminum plate in ships?

marine grade aluminum plate deformation according to the different manufacturing process can be divided into aluminum plate and the casting aluminum plate, due to Marine aluminum plate on the strength, corrosion resistance, weldability, etc have special requirements, so the Marine aluminum plate with aluminum – magnesium alloy, aluminum – magnesium – silicon alloy and aluminum and zinc, magnesium alloy, including 5 series aluminum – magnesium alloy in the most widely used on ships, so, 5 series Marine aluminum plate what are the characteristics?

What is 5754 thick aluminum plate?

The 5754 thick aluminum plate is applied to the ship. The aluminum has very good corrosion resistance, which reduces the corrosion of the seawater atmosphere to a certain extent and prolongs the service life of the ship. At the same time, the weight of aluminum is 1/3 of steel, but the strength is double that of steel. This reduces the ship’s own weight, which speeds up the ship speed, reduces fuel and increases the load. In addition, the 5754 thick aluminum plate has good processing properties and weldability, which greatly improves the safety of the ship
