Material properties of the metal plate

Nameplate material aluminium and its alloy in the medium containing halogen ions by pitting, and the oxide film is the case, the existence of the second phase is related to the annealing temperature and time, alloy. Nameplate material if in a passive state of iron, and in the solution existence of Cl - together 、 Br- ,我- - - - - - Or ClO4 - It in acidic, neutral and alkaline solution were subjected to corrosion pores. Titanium holes corrosion occurs only in good solution in high concentrations of chloride ( 42% MgCl2; 61%CaCl2; ZnCl2 were 86% mass fraction) And with a little water in the methanol solution of bromine. Nickel in rich in Cl - 、 Br- ,我- - - - - - In the solution of the anodic polarization, small hole corrosion. Cr and Ni, Mo and N content in stainless steel, coming to the corrosion resistance of corrosion holes nameplates. Forward Cr passivation membrane stability, Mo restraint metal dissolution. Forward pitting function elements:, Si, Cr, Mo, Ni, V N, Ag promote pitting elements: Mn, S, Ti, Nb related content: metal label materials used in the metal label material is commonly selected for aluminum, copper, stainless steel plate. Chooses the aluminum and aluminum version is generally brushed aluminum plate, with the line of fine grain, make printed aluminum is very exquisite and beautiful. The light, soft, beauty is characteristic of aluminum. The aluminum surface and a layer of protective film to protect card will not be scratched. We usually is to use pure copper and copper to make, and make LaiChunTong effect is, of course, with classical beauty, usually on the surface of plating a layer of bronze, that is more interesting. Stainless steel plate has two kinds: one kind is 304 stainless steel, the stainless steel quality are the best, after wind and rain there will be no changes. But the price is a bit on the high side, and another kind of stainless steel is too cheaply, are made to the effect of less than 304, but make the result is right also. Sign function is as follows: 1, the sign is a kind of media function, by the people for a long time to understand the sign position to give you a warning and propaganda, let us see the place will know what is the company's brand. 2, have the function of marking and identification of sign. When we went to a strange place, is in one of the biggest sign, he can let us better identify the direction and location, so as not to have no sense of direction. 3, also bear the business promotion effect of sign and commercial sign reflected in People's Daily life, can be at the gate of the shopping mall where bank hotel hotel as billboards displaying its need to promote a product or service. Bargain signs, can produce can't estimate profits, is a real small cost to achieve high profits.
