Precision Alloy (GB/T15018-1994)
Precision alloy is a class of metal materials which have special properties and specific intended uses. It includes a variety of metal alloys that are commonly used in various industries. The precision of these metal alloys is determined by their various and distinct mechanical, physical, and chemical properties. Precision alloy is usually composed of two or more metals and often includes specialized elements that give it specific characteristics or qualities.
Precision alloy is utilized in many industries, including automotive, electronics, aerospace, medical, and others. As a result, it must meet certain standards of quality and performance. According to the GB/T15018-1994, precision alloy must possess the properties needed for its intended use and must meet specific performance and functional requirements.
Precision alloy usually has very high levels of elasticity and toughness. It is also light, resistant to shock and vibration, and also resistant to many corrosive elements. Precision alloy has superior thermal conductivity and electrical conductivity, making it ideal for electrical applications. Additionally, it has good fatigue life and does not easily deform under load.
The GB/T15018-1994 sets out the requirements for precision alloy. These include the chemical composition, physical and mechanical properties, dimensional range and tolerances, surface fidelity and finish, organizational analysis, and others. The organization of analysis requires that the alloy should be tested to determine the amount of carbon, silicon, manganese, and other metals present in the alloy. The physical and mechanical properties must include flatness, elongation, tensile strength, hardness, fatigue strength, and other properties. The dimensional characteristics should include the specification tolerance and surface finish, which must also meet the specifications set out in the standard.
In addition to meeting the requirements of the GB/T15018-1994, the precision alloy must also have a good casting and machining quality, wide temperature range, and good wear and tear resistance. Precision alloy is used in various fields and industries nowadays and it is especially important for precision and miniaturization of industrial parts and other components. Therefore, it is important to carefully consider all the requirements and properties mentioned in the standard when selecting precision alloy.
