5052-H32 Aluminum Bar

5052 represents the brand of the product, and the word “5” indicates that the modified product belongs to the aluminum-magnesium alloy product. According to the chemical composition, it can be seen that the magnesium alloy content of the product is between 2.2-2.8%, and the density is 2.68. Generally, enterprises take the median value of 2.5% magnesium alloy content in the processing process, so this series of aluminum plate can become AlMG2.5.
H32 represents the processing state of the product H can be understood as incomplete annealing and work hardening state, that is, the product has been annealed, the hardness is degraded for processing molding, and in order to avoid the hardness of the product is too soft, and the appropriate work hardening. 32 means the modified product has been stabilized and the hardness is 1/4 hardness.
Grade of hardness: Usually H behind last Arabic numerals and hardness value is directly related to, such as H32 H34 H24 h18 last Arabic numerals represent the hardness, under the same brand of aluminum plate inside the Arabic numerals, the greater the hardness is higher, such as H34 hardness is higher than that of the most soft H32 state directly become zero state, more suitable as a stretch material. Arabic numerals take even numbers, 2, 4, 6, 8 the industry term becomes 1/4, 1/2, 3/4 full hard.
It can be concluded from the above that 5052H32 aluminum plate belongs to the aluminum magnesium alloy with magnesium alloy content near 2.5%. It has been stabilized by incomplete annealing and hardening processing, and its hardness is 1/4. Usually the product has strong corrosion resistance, good surface oxidation effect, good bending ability, 90 degree bending does not crack, is a typical sheet metal material, suitable for chassis cabinets and other bending products of classical materials.

Aluminum is a silver-white light metal, relatively soft, density 2.7g/cm3, melting point 660.4℃, boiling point 2467℃, aluminum and aluminum alloys have many excellent physical properties, has been very widely used. Aluminum has good reflection performance of light, reflecting ultraviolet light is stronger than silver, the purer aluminum is, its reflection ability is better, and the method of vacuum aluminum plating is commonly used to make high-quality mirrors. Vacuum aluminized film combined with polysilicon film becomes a cheap and lightweight solar cell material. Aluminum powder can maintain a silvery luster, often used to make paint, commonly known as silver powder. Pure aluminum conducts electricity very well, second only to silver and copper. In the electric power industry, it can replace part of copper for wires and cables. Aluminum is a good conductor of heat. It can be used to make various heat exchangers, heat dissipating materials and civil cookers in industry. Aluminum has good ductility, can be drawn into a fine wire, rolled into a variety of aluminum products, but also can be made into thinner than 0.01mm aluminum foil, widely used in packaging cigarettes, candy, etc.. Aluminum alloy has some better properties than pure aluminum, which greatly expands the application range of aluminum. For example, pure aluminum is soft, when a certain amount of copper, magnesium, manganese and other metals are added to aluminum, the strength can be greatly improved, almost equivalent to steel, and the density is small, not easy to rust, widely used in aircraft, cars, trains, ships, artificial satellites, rockets manufacturing. At -196 ° C, some steel is as brittle as glass, while some aluminum alloys increase in strength and toughness, making them cheap and lightweight cryogenic materials that can be used to store liquid oxygen and hydrogen for rocket fuel.
