Aluminum profiles are good and bad, and the number of aluminum profiles is huge, it is impossible to check one by one. In order to reduce unnecessary trouble, it is very important to choose a good manufacturer. If we know some factors affecting the quality of aluminum material, we can buy a safe material.
6063 alloy is Al Mg Si as the main element of the alloy, each element has a certain range of content, the price of magnesium is high. In order to reduce the cost, some manufacturers to reduce the amount of magnesium to the minimum allowable content. In some cases, the magnesium content is lower than the allowable minimum content. There are also factories in the alloy plus waste wires and waste pots waste aluminum pot, basically can not talk about 6063 alloy. The mechanical strength of aluminum profile is very low, so it can be easily bent with two hands and one bend, commonly known as "noodles". That's one reason why aluminum profiles can be cheaply cheaper.
Regular aluminum manufacturers, in the preparation of alloy components, there are internal standards, is in the range of various elements, each plant has their own smaller range of change, aluminum, magnesium, silicon between the three is strict in proportion, each plant has its own data, mutual confidentiality. With qualified alloy, quality can be guaranteed, otherwise the quality will not be processed.
Aluminium alloy smelting furnace
It is also essential for the 6063 alloy to be melted and what furnace is used. Now the domestic furnace has the level of 40s and the 90s level, and the worst manufacturer uses the original crucible boiler. There are coal burning, oil burning, gas burning and electric heating smelting furnace. Some of the stoves have chimneys, some of which have no chimneys. Generally used for square furnace (rectangular furnace), advanced for round furnace, some round furnace can tilt aluminum water. Tonnage has one ton, two tons, five tons, ten tons, twenty-five tons and fifty tons of aluminum melting furnace. It is more advanced that the 6063 alloy is made up of a static furnace and a static furnace under the aluminum melting furnace. In this furnace, the slag can be removed and degassed, and then the aluminum rods are then cast for extrusion. The quality of the alloy made from the original coal fired stove and the modern round furnace is absolutely different. Ordinary stoves, no matter what fuels they burn, should have chimneys. Most of the waste gas produced during the combustion of fuel can be discharged from the chimney. It is one of the reasons for the low quality of aluminum, which is one of the reasons for the poor quality of aluminum profiles, which is one of the reasons for the poor quality of aluminum profiles.
