|Benefits to aluminum metal foam
Foamed metal aluminum is really a porous metal material. The foamed aluminum after foaming is 8 times the volume of traditional aluminum profiles. It may efficiently save non-ferrous material resources and make realistic use. It has good development prospects. The air permeability with foamed metal aluminum is very high. Almost all of them are connected pores as well as the specific surface area of the pores. Large, the bulk density of the material is small. Foamed aluminum metal must be used in the manufacture associated with purification, filtration, catalytic help, electrodes and other units in petrochemical, aerospace, in addition to environmental protection. Compared considering the general sintered porous metal, the metal material containing foamed pores includes a higher porosity and a larger pore size, up that will 7 mm. Since foamed metal is usually a two-phase composite material made up of a continuous phase of the metal matrix framework and a dispersed or continuous cycle of pores, its properties rely on the metal matrix, porosity and pore structure used, and so are affected by the preparing process. Generally, the mechanical properties connected with foam metal decrease with all the increase of porosity, and its electrical conductivity as well as thermal conductivity also reduce exponentially. When the steel foam is under stress, the force-receiving area increases because of the collapse of the pores as well as the material strain hardening consequence makes the metal foam own excellent impact energy compression characteristics.
Application fields regarding aluminum metal foam
JUST ONE. Electrode material. The excellent electrical conductivity allows aluminum foam for being widely used as electrode composition materials for new batteries for example nickel-zinc batteries and electric double-layer capacitors. At existing, aluminum foam has recently been tested by many nickel-zinc battery manufacturers and place into mass use. At the same time frame, foamed aluminum is supposed to be popularized and applied being a electrode current collector pertaining to electric double-layer capacitors; also, foamed aluminum has a really broad prospect as a strong electrode material for electrolytic healing period of aluminum-containing wastewater.
TWO. catalyst. In many organic chemical reactions, people make an effort to directly use foamed aluminum having a large specific surface community to replace punched aluminum like a catalyst for chemical reactions; Foamed aluminum as a new photocatalytic air purification carrier has also been successfully applied.
THREE OR MORE. Thermally conductive material. Foamed light weight aluminum has excellent thermal conductivity, so that it is a flame-retardant material using excellent performance. It have been used in many superior fire-fighting equipment abroad, especially like a flame isolation device with excellent effects; in supplement, people use the exceptional thermal conductivity of foamed aluminum And apparent permeability, designed into heat dissipation elements for motors and electrical appliances.
4. Noise decrease and shielding materials. The sound waves are diffusely reflected for the surface of the foamed metal, and through the principles of expansion silencing and microporous silencing, the outcome of silencing is accomplished; the shielding performance of aluminum is close to that of silver, in fact it i an excellent electromagnetic protecting material.
5. filter material. Aluminum foam products, which have excellent structural characteristics and therefore are basically harmless to the skin, have also been with success used as medical filtration system materials; at the exact same time, foam aluminum has a good future in the required forms of water purification units.
6. Fluid pressure load material. The dispersion and padding effect of foamed aluminum on fluids can make it an excellent decompression security device for various strain meters.
Foamed aluminum has quite a few excellent structural properties and is basically harmless to the skin, so it is trusted in various industries. Should you be looking for high-quality aluminum metal foam in the reasonable price, Zhu Xia Metallic products Co.,Ltd. will provide you the best products.
