What's the Panic? Tungsten is the best replacement of  Lead

Lead:Is toxic to humans and wildlife .

Creates environmental concerns for disposal

Contaminates soil and water

Has expensive remediation costs mandated by Federal agencies

Why Lead Replacement?

Lead is ranked number two on the U.S. Government's Top 20 Hazardous Substances Priority List. The U.S. Environmental Protection Agency has listed lead as a toxic chemical and set very restrictive threshold limits for concentrations in air, soil, water and vegetation. Lead is also under strict limitations in unleaded gasoline, paint, and general exposure in workplaces.

What Can Be Used As A Lead Replacement?

Lead's popularity is mainly due to its outstanding physical properties: high density, ease of casting and fabrication, and malleability.

Tungsten is a suitable material for lead replacement applications. It has an even higher density than lead. However, due to its extremely high melting temperature, molding tungsten into a shape is complex and costly. Still, tungsten can be formed into solids through a process called sintering. This is where tungsten and other metal powders are pressed into shape and bound in a special furnace.

Another approach to using tungsten powder as a lead replacement is currently used by many companies that manufacture non-toxic thermoplastic composite materials. These materials are mostly used for injection molding processes contain a variety of polymers and fillers.

A new approach for low-volume production of non-toxic lead replacement parts is now available.

Chinatungsten offer the ability to pour lead density by simply mixing powder with suitable polymers. The material can be rigid or flexible, poured or injected, cured quickly or slowly, and is available in a variety of kit sizes.
