I'm reaching out to gather comprehensive details and pricing information for tungsten alloy products. We're particularly interested in understanding the different grades you offer, their specific applications, and any customization options available. Additionally, it would be helpful to know your standard lead times, minimum order quantities, and any bulk pricing options that you might have. Furthermore, if you could provide insights on the specifications, such as density, hardness, and any certifications your products hold, that would be great. We're looking to evaluate potential suppliers and their capabilities to meet our needs effectively. Thanks in advance for your prompt response!
