Tungsten Alloy Riveting Bucking Bar

In aircraft maintenance, the Tungsten heavy Alloy Bucking bar will be under considerable pressure while providing support. In this case, the high-density tungsten alloy will not be too soft, the Tungsten heavy Alloy Bucking bar will not wear quickly, and can provide the necessary support at the same time. Also, the high-density tungsten alloy will not be too hard and brittle, and it will not easily break during maintenance. High-density tungsten alloy is the most suitable material.

Tungsten Alloy Riveting Bucking Bars are made of high-density tungsten alloys. The specific shape is usually determined by the location and convenience of the rivet, and the size and size depends on the size and material of the rivet gun. These heavy metal alloys can improve machinability and provide higher rigidity, lower vibration, higher damping, and reduced thermal expansion performance.

Powder metallurgy process
Raw material preparation:

Tungsten powder (particle size 1-5μm) + bonding metal (Ni/Fe powder) ball milling mixing (time ≥8h, uniformity >99%).

Forming:

Cold isostatic pressing (200-300MPa) → green density reaches 60-70% of the theoretical value.

Sintering:

Liquid phase sintering (1450-1500℃/H₂ atmosphere), Ni-Fe melt fills the gap between tungsten particles, and the density is >98%.
Precision machining challenges
Turning difficulties:

High hardness leads to fast tool wear → Use diamond-coated blades (life increased by 3 times).

Surface treatment:

Electrolytic polishing reduces roughness (Ra <0.2μm) and reduces workpiece scratches during riveting.

The tungsten alloy riveting bucking bar has high density, high strength, and low recoil characteristics as its core advantages. Its density can reach twice that of ordinary steel, with a smaller size but greater weight, and it is suitable for operation in small spaces. The rounded corner design ensures safety, and the polished working surface reduces vibration transmission and operating fatigue. High ductility allows it to withstand high-frequency impacts without easy deformation. It can form a stable riveting structure with a rivet gun.

Tungsten alloy riveting bucking bars are widely used in aerospace, automobile manufacturing and heavy machinery assembly fields. In the riveting of aircraft fuselage, its high-density characteristics can accurately control the rivet molding to reduce the impact of vibration on precision components; it is used for riveting operations in narrow spaces such as engine compartments in the automobile industry; the heavy machinery field relies on its impact resistance to achieve high-strength connections.
