Exploration of Heat Transfer Characteristics of Metal Foam and Its Application in HVAC Industry
Metal foams are attracting attention in engineering applications due to their low density, high volume ratio and high thermal conductivity. In the heating and cooling industry, compact heat exchangers, solar thermal facilities and thermal energy storage are the 3 core directions.

Introduction and Pretreatment of Nickel Foam
Nickel foam is an excellent sound-absorbing material with a high absorption coefficient at high frequencies; its sound-absorbing performance at low frequencies can be improved by the design of the sound-absorbing structure. Nickel foam is also one of the best electrode materials for cadmium-nickel batteries and hydrogen-nickel batteries. Nickel foam itself has many excellent characteristics.

About types of metal foam
metals foam are prepared by sintering, electroplating, pressure casting, and foaming methods. Among them, the electroplating method and the powder metallurgy method under the subdivision of the foaming method are common. The former by adding foaming agent to the molten metal to produce metal foam; the latter through the electrodeposition process in the polyurethane foam skeleton copied into metal foam. At present, the metal foam has been widely used in aluminum nickel, copper and its alloys, in addition to iron, magnesium, titanium, steel, lead and so on also have a certain application space,

Is metal foam a metal?
Metal foam is a metallic material with special properties, which has both metallic and foam properties, hence the name foam metal. So, is metal foam a metal?
The answer is yes. Metal foam is made of metal material, which has the properties of metal such as electrical conductivity, thermal conductivity, strength and so on. At the same time, the metal foam has a large number of tiny pores inside, forming a structure similar to foam, which makes the metal foam has the properties of light weight, high specific strength, good heat insulation and so on.

Metal foam: A new metallic material that is both “strong” and “lightweight”.
Metal foam has a unique structure, combining the characteristics of metal and the functional properties of porous materials. Metal foam belongs to the porous metal materials, the internal porosity can be as high as 90% or more, the shape is like “foam” or “honeycomb”, breaking the traditional concept of dense structure of metal, both metal “strong” characteristics and bubble “light” characteristics, is a new structure-function integration of metal materials. “It breaks the traditional concept of dense structure of metal and has both the characteristics of metal and bubble, which is a new type of metal material with structure-function integration.

What are the common areas of application for this new material, metal foam?
Metal foam, as a new type of material, has a very wide range of applications. Because of its own characteristics, it not only has very good compression resistance, but also has very good plasticity and additivity; at present, it is also widely used in aerospace and military fields, and as a kind of lightweight construction material, it is also widely used in various industrial fields.

Exploring the Strength of Aluminum Foam: A Versatile Material for Modern Applications
Aluminum foam is an excellent material that has received widespread attention from various industries due to its unique properties. It is a lightweight porous material composed of solid aluminum with a large number of interconnected pores. This innovative material combines strength, durability and versatility, making it ideal for a variety of applications.

The Future of Sound Absorption: Developments in Aluminum Foam
