The right format for your process

Lead alloys are essential for many branches of industry due to their special properties. In electronics, they are used as a reliable soldering material, particularly in the production of printed circuit boards and electrical connections. In mechanical engineering and the automotive industry, their high density and stability ensure durable components that can withstand high loads. In radiation protection, especially in medical technology, lead offers effective protection against radiation due to its dense structure. Lead-containing alloys also play a key role in electroplating and in the construction industry, for example for anti-corrosion coatings or as a sealing material. Feinhütte supplies these alloys in various formats such as ingots, blocks, wires or rods, tailored to specific industrial requirements.

According to the Chemicals Prohibition Ordinance (§ 5 ChemVerbotsV), lead-containing substances may only be sold to commercial customers with the appropriate expertise. Sale to private individuals is prohibited by law. We therefore reserve the right to request appropriate proof when placing orders.

Frequently asked questions (FAQ)

Pure lead has a low electrical conductivity; additives such as silver or tin significantly improve this. Alloys are specially formulated for optimum conductivity for applications in electrical engineering.

Lead alloys vary greatly in melting point, depending on their composition. Pure lead melts at approx. 327 °C, PbSn alloys (e.g. Pb60Sn40) can have significantly lower melting points of around 183-238 °C. Lead-bismuth alloys have even lower melting ranges, which makes them ideal for soft solders.

Lead alloys are widely used in various industries:

  • Radiation protection and medical technology: shielding such as X-ray aprons or medical devices that block ionizing radiation.

  • Cable and energy technology: sheathing and shielding of cables for protection and electrical insulation.

  • Mechanical and plant engineering: plain bearings, seals and counterweights with high wear resistance.

  • Electrical engineering and electronics: Solders and connections with good flow properties and conductivity.

  • Foundry industry: casting molds and lead casting products with defined material properties.

These versatile areas of application continue to make lead alloys an important material in industry.

The use of lead is not generally prohibited, but it is subject to strict legal regulations. In the European Union, for example, the RoHS Directive and the REACH register apply, which restrict or regulate the use of lead in certain products and applications.

Lead is still indispensable in many technical applications, particularly in radiation protection, battery technology and electrical engineering. In contrast, there are often bans or strict limits for food contact or toys.

 

We manufacture lead alloys both in accordance with industry-specific standards and in compliance with legal requirements such as RoHS and REACH, insofar as this is relevant to the application.

Lead itself is toxic and must be processed safely. Our lead alloys are manufactured, processed and recycled under strict safety and environmental regulations. Alternatives are recommended for applications with direct skin contact or food contact.

The sale and purchase of lead is subject to legal regulations, as lead is considered a toxic heavy metal. In principle, commercial companies are allowed to purchase lead for technical and industrial applications that comply with the applicable environmental and safety regulations.

Private individuals are often subject to restrictions or require special permits, depending on the country and intended use. Trade in lead is also subject to reporting and verification requirements to ensure environmental and health protection.

We recommend that you find out about the national and European regulations before making a purchase and seek specialist advice if necessary.

 

Yes, depending on the application, various alternatives to lead alloys are available, particularly for environmental and health reasons.

  • Plastics with lead substitutes or composite materials are sometimes used for radiation protection, but these often require a higher thickness or lower density.

  • In the field of solders, there are lead-free alloys based on tin, silver, copper or indium, which are increasingly becoming standard and meet the requirements of the RoHS Directive.

  • In mechanical engineering, bronze or brass alloys are sometimes used as a substitute when lead is used as a soft or sliding metal.

The choice of alternative depends heavily on the specific technical requirements.
