Common RF coaxial connector conductor material selection

With the increasing development of 5G communications artificial AR intelligence and other fields, the connector is involved in a very wide range of fields, in different environments need to be used to RF coaxial connectors for signal transmission, thus achieving full signal coverage, the true realization of AR artificial intelligence, for different scenarios Wuhan Lixin electronic R & D team, the main choice of brass, phosphor bronze, beryllium bronze and stainless steel, these materials, the next small introduction to the appeal of several materials used: brass brass is soft and easy to machine, known as "easy to cut brass", and beryllium bronze compared to the thermal contact of brass, and beryllium bronze. Next, I'll introduce to you the appeal of several materials used: brass brass texture is soft and easy to machining, known as "easy to cut brass", and beryllium bronze compared to the brass thermal contact and thermal conductivity and electrical conductivity are good; relative cost of making out to be a lot lower, commonly used in the use of the environment is not harsh environment connector body Tin phosphor bronze, shell, outer conductor processing phosphor bronze, the alloy material is soft, can be obtained through cold processing (pressure, bending) to get up the stress; due to the tin phosphor bronze has a certain degree of softness and toughness. When the production budget does not allow or electrical properties do not necessarily require the use of beryllium bronze can be replaced by tin phosphor bronze, for example: larger center pin insert holes (N-type 7/16DIN 4.3-10, etc.), elastic contact (eg: MCX contact head 4.3-10 contact head, etc.) beryllium bronze beryllium bronze has good electrical properties and heat transfer properties, has a very good elasticity, fatigue resistance, with a strong Corrosion resistance (except ammonia, strong acids and alkalis); good heat transfer properties and elasticity so that it will not be melted in high temperature environment, and some other properties will not be damaged by high temperature. Beryllium bronze is commonly used in: contact holes, i.e. jacks (where electrical contact is made), elastic pins, and conductors at the outer end of interfaces. It can enhance the contact of the product, mainly used for: SMP female connector MCX connector contact head All female connector center pin, etc. Stainless steel material Stainless steel is suitable for the connector industry where the hardness of the material is required to be high. It is characterized by high stability, high melting point and excellent corrosion resistance, some connector shell parts will use stainless steel. Stainless steel is generally used for connector shells, nutshells and outer conductors, which can enhance the service life, mainly used for: military grade, military grade, test grade and other fields. Suzhou Huicheng Yuan Electronic Technology Co., Ltd. supports customized design and production of connectors in all fields, and our products are widely used in 5G communication, aerospace, AR artificial intelligence and other fields.
