Whilst brass is known for its attractive colouring and versatility, it is a much more malleable metal than other types so it is important to ensure that all machining bars are handled carefully to avoid the risk of damage. Therefore, the proper care and maintenance of your brass bars should begin the moment you receive them.
After receiving a delivery of brass machining bars, you should immediately check that they have been packed properly, such as each bar being wrapped in a plastic coating. Check the packaging and coating for any damage, as this can travel through to the metal inside. Ensure that both the packaging and pallets are not damp, as this can occasionally cause staining. Brass should always be stored indoors, preferably raised above the ground.
When handling brass machining bars, it is important to prevent them from banging into or scraping against each other as this can dent the surface of the metal. It is also highly important to avoid allowing brass to come into contact with ammonia or any ammonia based products. Failure to do so can result in the brass developing stress corrosion cracking, which renders the metal useless.
Finally, the best way to keep your brass materials looking brand new is to regularly clean the bars to remove any dirty build-ups. Ensure that you use the least harsh method possible, as abrasive cleaners can remove the lacquer that is applied to brass to protect it from tarnishing. A mild detergent mixed with warm water is generally sufficient for removing dirt and oil, and special brass polishing clothes are handy for keeping up the metal’s shine.
