In recent years, adulteration, forgery and shoddy workmanship in the aluminum, magnesium and manganese industry have been one of the most ugly acts in the industry's production and sales, the bad merchants passed off the low brand as the high brand, recycled aluminum as the national standard, used cheap low-temperature paint and paint film, Short Weight, easy to crack, easy to fade, no after-sale guarantee, etc. , although it does not represent the real and objective present situation of the current aluminum, magnesium and manganese industry, its existence has played an unneglectable destructive role in the healthy development of this industry, threatening the property and personal safety of the majority of owners and processing households, people should pay attention and refuse to use low-priced and low-quality products. We will take the initiative to promote relevant professional knowledge, refuse to adulterate, counterfeit and shoddy, firmly defend the healthy development of aluminum, magnesium and manganese industry.
1060 is industrial pure aluminum, does not contain other metals, low strength, but corrosion resistance is the best 3003 more than 1% of manganese, is aluminum-manganese alloy, strength medium, belong to rust-proof aluminum 3004 more than 1% of manganese and 1% of magnesium, is aluminum-manganese Alloy, strength, belong to rust-proof aluminum
H18 for hard aluminum, H24 for semi-hard aluminum H18 fold 180 degrees, will break or crack H24 fold 180 degrees, break without crack H18 bend will rebound, H24 bend without rebound
1060 and 3003 have no magnesium, the board is white and bright 3004 contains magnesium, the board is dark and bright
3004 as a result of material surface special, film adhesion is generally poor, scratch resistance is also poor.
