The method of judging the quality of aluminum profile

Posted time:2021-04-01 Page View:790

Aluminum has good or bad, and the purchase of aluminum is huge, it is impossible to view one by one, in order to reduce unnecessary trouble, it is very important to choose a good manufacturer, assuming that the understanding of several factors affecting the quality of aluminum profile, you can buy the centering information.


Alloy elements: 6063 alloy is aluminum magnesium silicon as the main elements of the alloy, each element has a certain planning of the content, the price of magnesium is high. Some manufacturers in order to cut costs, the amount of magnesium to the minimum allowable content. In some cases, the magnesium content is lower than the minimum allowable amount.

Some factories add waste wires and waste aluminum POTS in the alloy, not 6063 alloy at all. The mechanical strength of the aluminum profile is very low, can be low to use two hands to bend a very simple bending, commonly known as "noodles" as soft. This is one of the reasons why aluminum extrusions are thousands of dollars cheaper.

Formal aluminum manufacturers, in the manufacture of alloy components, have internal specifications, industrial aluminum is in the content of various elements in the planning, each factory has their own small change planning, aluminum, magnesium, silicon three proportion requirements are very strict, each factory has its own data, confidential each other.

The alloy made of qualified formula can guarantee the quality, otherwise how to process later, the quality can not go up. Aluminum alloy melting furnace

How to melt the 6063 alloy and what furnace is used is also crucial. Now the domestic furnace has the level of the 1940s and the level of the 1990s, and the worst manufacturer uses the original crucible boiler. There are coal - burning, oil - burning, gas - burning and electric heating furnaces.

Some stoves have chimneys, others have none. Generally used for more square furnace (rectangular furnace), advanced for the round furnace, some of the round furnace can be inclined to pour aluminum water. In terms of tonnage, there are 1 ton, 2 tons, 5 tons, 10 tons, 25 tons and 50 tons of molten aluminum furnace. More advanced, industrial aluminum profile in the aluminum melting furnace under the addition of a static furnace, static furnace important manufacturing 6063 alloy, can be in the furnace slag degassing, static, and then cast aluminum rod, for kneading use.

The quality of the alloy produced in a primitive coal stove is certainly not the same as in a modern round stove.

In general, no matter what fuel is burned, there should be a chimney. Most of the waste gas and residue from the fuel incineration process can be discharged from the chimney.

If there is no chimney exhaust waste residue all melted in aluminum water, so cast aluminum rod for kneading, there are severe slag bubbles inside, which is one of the reasons for the low quality of aluminum profile, which is also one of the reasons for the low price of aluminum.
