1.Combining the wear resistance of copper alloys with the high mechanical strength of steel;；
2.Different copper alloy materials, including low friction lead copper alloys, can be cast according to the requirements of the working conditions；
3.Due to the different friction coefficients of the inner and outer materials, it can prevent the bearing from shifting and running around the outer circle under high load and low-speed conditions；
4.Solid lubricants can be covered or embedded on the working surface as needed to achieve self lubrication；
5.Compared to pure copper sleeves, it has a cost advantage and saves resources；
6.Post processing can be carried out, such as heat treatment of steel substrate, alloy layer machining, etc；
7.Copper alloy casting can be carried out in one or more layers on different or complex surfaces according to design requirements；
8.Similar to traditional copper sleeves in terms of usage characteristics, it can be suitable for working conditions under different temperatures and lubrication conditions；
9.Compared to pure copper sleeves, it has better mechanical load-bearing performance, especially in terms of impact strength.

1. Adopting a new type of double alloy guide plate with a steel substrate and a high-strength copper alloy working surface, cost savings of over 35%!
2.Embedding high-quality graphite columns, utilizing independently developed unique graphite arrangement technology and graphite hole processing methods, combined with advanced vacuum immersion technology, to fully unleash its self-lubricating guiding performance.
3.The Junheo double alloy guide plate adopts multiple sintering composite processes, which can tightly bond atoms, increase product strength, and make it more wear-resistant during use.
4.The surface hardness testing of copper alloy meets the standard, with HB80~100 or above; Parallelism and flatness can be guaranteed; Heat resistance test, proving that the shape remains unchanged and the coefficient of expansion is extremely small; Bending test, no peeling occurred on both the front and back sides; Customization can be made according to customer's drawings.
