3105 aluminum alloy has good corrosion resistance, good plasticity and processability, and the performance of gas welding and arc welding is good. 3105 aluminum has slightly higher strength than 3003 aluminum, others properties are similar to 3003 aluminum alloy. 3105 aluminium has good anti-rust property, good conductivity, electrical conductivity can be up to 41%, 3105 aluminum sheet has high plasticity in the annealing state, in the semi cold hardened, the plasticity is still better, it has low plasticity, good corrosion resistance, good weld-ability and poor cutting properties in cold hardening state.
The common product of 3105 aluminum alloy are 3105 aluminum sheet plate and 3105 aluminum foil and 3105 aluminum strip. The material temper of aluminium 3105 are O, H12, H14, H16, H18, H19, H22, H24, H26, H28, H32, H34, H36and H38. The thickness is 0.1-500 mm, the width is 100-2600 mm, the length is 500-16000 mm. The typical final product are bottle cover, beverage bottle cap, cosmetic cover, etc. The market applications include room partition, baffle, movable room board, gutter and downpipe, sheet forming parts, bottle stopper, etc.

Roofing sheets are plates that may immediately withstand roof hundreds. The roofing sheet is positioned at the roof of the residence and is commonly made from metal consisting of aluminum magnesium manganese or alloy, so it's also known as as aluminium roofing sheet. Aluminum-magnesium-manganese sheet alloys for roofing generally undertake the Coil covered method, which has the advantages of good shade manipulate, uniform film, excessive first-rate stability and environmental protection. The sort of coating normally used PVDF fluorocarbon paint containing more than 70% of fluorocarbon resin.
The extremely good functions of aluminium roofing sheets are:1, wonderful climate resistance and anti-corrosion.Validated via practice, the aluminum roofing sheets have established top weathering overall performance beneath a diffusion of climatic conditions, showed precise corrosion resistance in the acid, alkali, salt chemical corrosion environment.2, terrific water-resistant performance.No water resistant layer is to be had in 15-90 diploma roof constructing.Three, The wind and earthquake resistance.Ninety tiers building facade ornament secure and dependable, capable of resist 12 robust winds.Four, properly hearth resistance overall performance.The material is hearth-resistant grade B1, is a non-flammable fabric.Five, splendid silencer and heat insulation performance.The porous foam middle has desirable noise attenuation and heat insulation residences.6, large place and light weight.Light-weight materials to reduce the development load.7, rich colours, lasting stability.Fluorocarbon paint coating, rich colors, clean floor, acid and alkali resistant, no mold.8, excessive longevity and electricity.Higher than similar products with longevity and strength.9, handy production.Products may be without delay nailed, drilled, sawed, planed and may be easily handled with special roof shapes along with facades and arc windows.
