FAQs about brass

Ordinary brass contains a low amount of lead, which is toxic to a certain extent. However, when brass products that meet the standards are used normally, the amount of lead leached out is extremely small and generally does not cause obvious harm to the human body. However, long-term exposure to brass with high lead content may be risky.

The brass commonly referred to is a copper-zinc alloy. The statement "100% brass" is not accurate. Generally, brass contains a small amount of impurities and some may contain lead, but not all brass contains lead. There is also special lead-free brass.

We use brass teapots of qualified quality , which are relatively safe under normal use. However, if it is leaded brass and improper use (such as long-term storage of acidic liquids), it may cause lead precipitation, so it is recommended to choose lead-free brass teapots and avoid acidic beverages.

Generally, qualified brass jewelry is safe to wear and contact with the skin. However, people who are allergic to metals may have allergic reactions, and long-term wearing of brass jewelry containing impurities such as lead may have potential risks. It is recommended to choose products with reliable quality.

Lead in brass exists in the form of a single substance or a compound, and its content varies depending on the type of brass. For example, some free-cutting brasses may contain about 1%-3% lead, mainly to improve cutting performance, but it will also affect its physical and chemical properties and safety.

In terms of safety, I think lead-free brass has more advantages. Leaded brass, such as H59 brass, has a cutting efficiency that is about 20%-30% higher than lead-free brass (such as C27400 lead-free brass). However, the corrosion resistance and food safety of lead-free brass are better than those of leaded brass , so it is necessary to determine which one is more suitable according to the specific application scenario.

We can conduct component testing through professional testing agencies to determine whether it contains lead. Generally, lead-free brass will have relevant logos. When purchasing, you can choose products from regular channels and with quality assurance. Checking the product manual and test report can also assist in judgment.

Qualified brass metal products are safe under normal use conditions. However, if the product contains harmful impurities such as lead and is used in an improper environment (such as high temperature, acid or alkali environment), it may pose a safety hazard, so you must choose products that meet the standards and use them correctly.

Normal use of brass products that meet the standards has minimal toxicity risks to the human body. However, if we are exposed to brass that contains excessive amounts of harmful impurities such as lead for a long time, excessive intake of heavy metals such as lead may have adverse effects on the human nervous system, blood system, etc.

Our export packaging system is specifically designed for high-value copper products, utilizing multi-layered industrial-grade protection. The standard process involves: wrapping the product with VCI (Vapor Corrosion Inhibitor) paper to effectively prevent salt spray corrosion during sea transportation; inserting reinforced wooden shafts into coil inner diameters and attaching high-strength plastic edge protectors to prevent edge damage; securely fastening the entire package to IPPC-marked fumigated wooden pallets with cross steel strapping for structural integrity; and finally, sealing the package entirely with waterproof stretch film to ensure moisture and dust resistance. All packaging is clearly marked with shipping labels and safety warnings, and combined with customized loading plans, maximizes container space utilization.
