Description
C17200 Beryllium Copper Round Sleeve – Precision Machined Bushing for High-Load Industrial Applications
The standard CuBe2 alloy used in the production of C17200 Beryllium Copper Round Sleeve complies with ASTM B196 and ASTM B534 industry requirements. The sleeve achieves 38–44 HRC hardness and 1280–1480 MPa tensile strength following expert age treatment. With a beryllium concentration of 1.80–2.00% and a thermal conductivity of 105–130 W/m·K, the component is non-magnetic and non-sparking and can withstand large loads. In-stock goods are sent within three to five days, and we provide in-house heat treatment, CNC machining, and bore honing services.
What Is a C17200 Beryllium Copper Round Sleeve?
The cylindrical C17200 Beryllium Copper Round Sleeve bearing bushing is made from a commercial-grade copper alloy and is very durable. To stabilise the internal structure and endure compressive stresses greater than 1000 MPa, the material employs solution annealing and precipitation hardening. Unlike traditional brass and phosphor bronze bushings, it strikes a balance between heat conductivity, chemical resistance, and fatigue resistance in complicated industrial working conditions.

Material Advantages Over Competing Alloys
Anti-Galling and Anti-Seize Performance: It is suitable for pumps and valves that are subjected to boundary lubrication conditions, as it effectively prevents galling and seizing when used with 300/400 class stainless steel shafts.
High Load-Bearing Capacity: The TH04 tempered structure is capable of withstanding compressive loads that exceed 1000 MPa, ensuring consistent performance in heavy-duty pivot and thrust applications.
Effective Heat Dissipation: The thermal distortion of moulded components is reduced and the duration of the injection mould cycle is shortened as a result of the higher thermal conductivity of the material compared to tool steel.
Special Safety Features: Its non-magnetic and non-sparking characteristics render it suitable for use in flammable, high-risk operation conditions and downhole detecting equipment.
Key Application Scenarios
Aerospace and defence: It is used in actuator casings and landing gear to provide constant impact resistance with minimum lubrication.
Hot runner bushings and core pins are required in the plastic injection moulding process to maintain product dimensional correctness and increase production efficiency.
Oil and gas downhole tools: shields internal precision electronic sensors from electromagnetic interference and minimises long-term vibration fatigue.
Industrial Pumps and Valves: Offers long-term, dependable service for fluid control equipment that is corrosion-resistant and dry-running.

Frequently Asked Questions
Q1: What's the difference between aluminium bronze and C17200?
A1: Its increased hardness and anti-galling properties allow it to operate reliably under long-term cyclic high loads.
Q2: What is the highest temperature at which it can operate?
A2: Mechanical characteristics are consistent at temperatures below 250°C; however, performance degrades at higher temperatures.
Q3: Is it possible to appropriately manage coverings that have been completed?
A3: There are no risks associated with solidly finished products. Dust-generating procedures necessitate protective measures.
Q4: Is lubrication necessary for operation?
A4: It is capable of supporting dry running and anti-seize operation, and it may extend the service life through regular lubrication.
Q5: How can the authenticity of C17200 material be verified?
A5: We provide comprehensive batch MTC reports that include hardness test data and composition data for verification.
