In June 2025, China’s light rare earth prices exhibited an oscillatory upward trend, while mid-to-heavy rare earth prices declined. As for average prices, praseodymium oxide averaged 460,250 yuan/ton, increased by 3.43% month-on-month; praseodymium-neodymium metal averaged 545,100 yuan/ton, increased by 3.42% month-on-month; terbium oxide averaged 7,181 yuan/kg, increased by 1.21% month-on-month; dysprosium oxide averaged 1,636,750 yuan/ton, decreased by 0.17% month-on-month.

The tungsten bucking bar is used in the riveting process in shipbuilding, primarily as a support tool during the installation of fasteners. It is placed on the back of the rivet to counteract the impact force from the rivet gun or hammer, forming a solid rivet head while reducing vibration and recoil, ensuring the strength of the connection. Tungsten alloy possesses characteristics such as high density, high hardness, wear resistance, and corrosion resistance, making it suitable for the high-strength riveting demands in shipbuilding involving steel, aluminum alloy, or mixed structures. Additionally, its environmentally friendly and non-polluting properties comply with international maritime environmental requirements.

In June 2025, most molybdenum product prices reached yearly highs. As for average prices, molybdenum concentrate averaged 3,838 yuan/ton-degree, increased by 7.12% month-on-month; ferromolybdenum averaged 247,050 yuan/ton, increased by 5.70% month-on-month; ammonium heptamolybdate averaged 238,750 yuan/ton, increased by 5.20% month-on-month; molybdenum powder averaged 440 yuan/kg, increased by 3.53% month-on-month.

The tungsten bucking bar is an indispensable professional tool in aircraft maintenance. It is typically used in conjunction with a rivet gun during the riveting process. When the rivet gun applies impact force to the rivet, the bucking bar provides a solid support surface and absorbs the impact energy, allowing the rivet to deform precisely and be securely fixed onto the materials being connected. This ensures the strength and precision of the riveting.
