Product Detail
The can is the most commonly used beverage packaging material in life.The aluminum belt of the cans is composed of three kinds of aluminum alloy with three different components: 3104 -can lid, 5052- can cover and 5182 -ring pull. Aluminum is the key of the canister.
The 3004 is a variation of 3003 alloy, form-ability, dissolves, good corrosion resistance, used for processing needs to have more good form-ability, high solder-ability good resistance to corrosion products. Because aluminum sheet itself has good oxidation resistance, it is very good to prevent the oxidation and corrosion of the carbonated beverage to the can.
The cans cover is made of5052 aluminum sheet

Quality requirement
The production of aluminum cans is more than 40 steps.The main processes related to the performance of aluminum sheet are: blanking, punching cup, thinning drawing, trimming, washing, external printing, internal spraying, drying,Neck, edge, etc. The aluminum sheet must have proper strength and good depth shaping, in order to ensure the continuous blanking process and the yield strength after baking.This includes thickness. The thickness of aluminum sheet is 0.25 ~ 0.30mm, can make it as the round material with a diameter of about 138mm, and then the punch cup is formed by two deep blanks. The reduction rate of the diameter is greater than 50%. after three times of stamping, the thickness is reduced to 0.08 - 0.10mm, the tensile thinning rate is over 65%. Due to the deep processing of the thinning drawing, the extensibility of the blank material is extremely low, so even the small inclusions can make the can broken, then make sure no breakage during trimming and turning.It also requires the material to have good plasticity. After several baking, the shaft of the tank must be kept under pressure and the pressure of the tank bottom is required 1.35kN, the pressure strength of tank bottom is 630kPa, to make sure that the canning and storage can be carried out smoothly.
Because of complexity of the thinning drawing process used in tank forming process, the comprehensive performance of aluminum sheet for tank is very strict. that is, the tensile strength is 270 ~ 310MPa, the yield strength is 250 ~ 300MPa, and the elongation rate is greater than 3%.
The ear rate is less than 2%. There is no visible ripple on the surface of the plate, and the inner and outer surface finish should be uniform, no oxidation, no visible inclusion, compression, spot and other defects.Plate thickness should be uniform,the tolerance must be within 0.005mm.
