Anti-rust aluminum features and uses

[China Aluminum Network] LF21 is a widely used rust-proof aluminum, its strength is not high, can not be heat-strengthening, high plasticity in the annealed state, and good corrosion, good weldability, poor machinability . Used for the manufacture of low load parts such as fuel tanks, tubing, liquid containers, etc., which require high plasticity and good weldability and work in liquid or gas media. Rivets can be made from wire rods;

LF13 has high corrosion resistance and good welding performance. Thermal conductivity, electrical conductivity is much lower than pure aluminum, can be used for cold deformation processing and can not be strengthened by heat treatment, suitable for welding structural parts;

LF5 and LF10 are aluminum-magnesium rust-proof aluminum (LF10 has slightly higher magnesium content than LF5), and its strength is comparable to that of LF3. It can not be strengthened by heat treatment, and the annealing state is high in plasticity. Semi-cold work hardening is of moderate plasticity, and the welding performance is good. LF5 is used. Make welding parts, pipes, and containers and other parts that work in liquids. LF10 is mainly used to make rivets;

LF6 has higher strength and corrosion resistance, and the plasticity is still good under annealing and extrusion conditions. The gas tightness and plasticity of the weld with TIG welding are acceptable. Good machinability. Used for welding containers, force parts, aircraft skin and skeleton parts;

LF5-1 is a non-heat-treatable aluminum alloy with a certain strength, good corrosion resistance, and good machinability. Anodized surface appearance, can be processed into optical mechanical parts, ship parts and wire clips;

LF2 and LF3 have higher strength than LF21, high plasticity and corrosion resistance, no heat treatment, and good weldability (LF3 has better weldability than LF2). It has good machinability under cold hardening and can be polished. Used for the manufacture of medium strength welds, cold stamped parts, containers, etc. working in liquids.

Silica Fume For Ceramics

Natural wollastonite products in accordance with the particle size can be divided into five categories of block particles, ordinary powder, fine powder, ultra-fine powder and needle powder, powder preparation method is mainly mechanical crushing. For wollastonite copy processing equipment are gravel mill, air flow mill, tell mechanical impact magic machine and so on. Mechanical crushing can be divided into dry and wet method, wet method of energy saving, protection of fibre aspect ratio; dry method does not agree with agglomeration. Shear-based mechanical crushing can obtain wollastonite ultrafine powder with high aspect ratio
