    We carry a wide variety of molybdenum and molybdenum alloy products in stock, and for these, there is generally no minimum order requirement. However, for custom orders, we typically set a minimum order value of $200. The lead time for stock items is usually 1-2 weeks, while custom orders usually take 3-4 weeks, depending on the specifics of the order.

    DFARS (Defense Federal Acquisition Regulation Supplement) compliance is primarily concerned with the sourcing of materials for defense-related applications in the United States. According to DFARS, certain materials used in defense must be sourced from the United States or qualifying countries.

    If you have specific molybdenum materials that are subject to DFARS, please let us know in advance and we will confirm.

    At Shanghai Yuepeng Tech, we take this responsibility seriously. We adhere to all applicable laws and regulations, including Section 1502 of the Dodd-Frank Act. Our company operates with a strict code of ethics and is committed to only partnering with suppliers who share our dedication to responsible sourcing. We support the initiatives and programs aimed at promoting “conflict-free” supply chains and work diligently to ensure that our products meet these standards.

    Molybdenum tungsten alloy is a solid-solution alloy composed of molybdenum and tungsten, both refractory metals. It combines molybdenum’s good ductility and workability with tungsten’s extremely high melting point and density, with properties varying based on tungsten content.

    The main advantage is better room-temperature toughness and machinability. Pure tungsten is very brittle and difficult to machine, while molybdenum tungsten alloys (especially with medium to low tungsten content) are easier to cut, forge, and work with, reducing manufacturing cost and difficulty.

    In a vacuum or inert atmosphere, it can be used at temperatures above 1800°C, depending on the tungsten content. However, in air, it oxidizes rapidly at high temperatures, limiting its use in oxidizing environments to typically below 400-500°C.

    Shanghai Yuepeng Tech, established in 2022 in Shanghai, China, is a specialized supplier and manufacturer of molybdenum and molybdenum alloys. With extensive expertise in supply and export, we offer competitive pricing and customized solutions tailored to specific requirements, ensuring outstanding quality and customer satisfaction. As a professional provider of refractory metals, specialty alloys, spherical powders, and various advanced materials, we serve the research, development, and large-scale industrial production needs of the scientific and industrial sectors.
