Porous foam metal series–Nickel foam

Short Description:

Nickel foam is a newcomer in the family of “porous metals”. It is made of nickel foam sponge with three-dimensional through-net structure through high-tech deep processing. The specific weight is 0.2~0.3, which is 1/4 of water, 1/3 of wood, 1/10 of aluminum, 1/30 of iron, and the porous structure has wide frequency sound absorption characteristics. It can be cut, bent, and simply adhered, and has strong thermal conductivity. The homogeneous three-dimensional mesh structure has the function of filtering, and the flow stability of gas and fluid.

Nickel skeleton hollow and metallurgical state interconnected, porosity up to 96-98%, bulk density is only one fiftieth of nickel, specific surface area, still maintain the good physical and chemical properties of nickel, so the characteristics of the new structure makes it a functional new material, with a broader range of applications.

Product Applications

Electrode Materials
Especially NiMH batteries are widely used in notebook computers, cell phones, electric scooters, electric cars, hybrid cars, etc.

Fuel Cell
Molten carbonate fuel cells generally operate at 550-700°C. Foamed nickel can be used as an electrocatalyst for fuel cells. Foamed nickel can be used to make bipolar electrode plate modification materials for proton exchange membrane manufacturing cells (PEMFC), electrode relay feeders for solid oxide fuel cells (SOFC), and electrode materials in electrolysis. In fuel cells, more surface area can also be used to produce hydrogen and synthesis gases.

Catalytic Carrier
Nickel foam has a unique open pore structure with low pressure input holes and inherent tensile strength and thermal shock resistance, making nickel foam a carrier for automotive catalyst converters, catalytic combustion and diesel black smoke cleaners. During the conversion of carbon monoxide and hydrocarbons during engine cold start, nickel foam catalyst carriers may outperform ceramic carriers due to their thermal conductivity, and in this sense, nickel foam may outperform or outperform high temperature resistant steel catalyst carriers. Other applications include foam catalyst carriers for Fisher-Topsh method, gas modification method, and hydrogenation of fine chemicals.

Flame-retardant and explosion-proof
At present, most of the foam metal, itself has flame retardant properties; also has a very good fluid penetration, it is based on these characteristics; nickel foam is widely used in the field of explosion-proof flame retardant, the most common such as acetylene or oxygen flame gas welding gas cutting; torch system, oil and gas recovery system and other fields, now can also be used for fuel, liquefied gas tanks porous fire, explosion-proof filling material. Nowadays, it can also be used as a porous fireproof and explosion-proof filling material for fuel and liquefied gas tanks.

Sound-absorbing and fireproof
Because of the gradient porous characteristics of foam and the non-combustible nature of metal, nickel foam has the dual function of sound absorption and fire prevention, and can be widely used in indoor KTV, cinema, auditorium, conference room and other places with high requirements for sound absorption and fire prevention performance. For example, Japan used nickel foam in the generator room, recording room and the Shinkansen sound absorption, etc. have obtained very good results.

Vibration damping
Nickel foam not only has a very strong stiffness, but also absorbs impact energy through its own damping properties when it is impacted. Therefore, due to its shock absorption and damping properties, nickel foam is also widely used in automobile bumpers, lift and transport system buffers, etc.

Lightweighting
Nickel foam composite panel has excellent properties such as high strength, light weight, fireproof, environmental protection, corrosion resistance, sound absorption, etc. It is an important new material to realize the light weight of rail vehicles, electric buses, ships, engineering equipment and buildings. The material can be welded, shaped and painted. The products have been successfully applied in the field of flooring of rolling stock, partition board and building decoration.
