We use CNC machining, the best easy to process, the hardness is too low, not good (listen to others say that some aluminum foam will stick to the knife, and some processing is not bright). Online check is said 6063, but to the aluminum shop asked about, say is 6061, buy 50 kilograms first, try to do, but the boss said seems to be another kind, beg you prawns help ah
5, as for aluminum rods or aluminum tubes, it depends on your quantity, quantity, or aluminum bar. Because aluminum is mostly seamed tube (not more seamless market), (the total cost of seamed tube lower) sometimes processed can see the seam line, unless you request is not high.
The 3 and two lines (2024, 2017, 2011) and seven (7075, 7050) and relatively high hardness, Brinell hardness of about 120-150, the two kinds of materials for aviation aluminum, the price is more expensive (40-90 /KG) range, easy cutting, brightness is also good, but the effect of oxidation as six series. Have not heard who used to do the lamp can also be excluded.4, so you are the most correct is to choose six lines of aluminum to do, and 6061 and 6063, I suggest using 6063, because the 6063 oxidation effect is better than 6061. Currently on the market is 6061 more larger in diameter than the aluminum rod and tube of 20MM (and most not GB, GB material oxidation effect, stable performance, but because of you) the amount is too small, can not find manufacturers directly customized, GB is not a good buy material. Ask more and you should find 6063.
1 LED lamp cup, the general can use a system (1060, 1070), six (6063, 6061) more2 according to the processing mode you said (CNC processing) can be ruled out with a line, three lines and five lines for the three series aluminum, aluminum Brinell hardness (HB) is generally not more than 70 degrees (Brinell hardness less than sixty or seventy degrees when machining will stick knives, knife and the surface is not easy to break light)
