Brass is nearly as bright as Gold. Brass is a common name for alloys of Copper and Zinc in several proportions, along with other elements like Lead or Silicon in minor proportions. It finds its use in a variety of places that range from decorations for its appearance to areas requiring low friction. Brass is highly preferred by designers in musical instruments for its durability and in areas where corrosion is troublesome. Since it is used profoundly in sensitive areas, there is this added need to protect and maintain it. Brass parts, especially those subjected to high temperature and atmospheric air, are the most susceptible ones for withering.
Brass parts exporters often find it difficult to guarantee the longevity of their products as it depends upon how well and how precisely it is maintained by the consumers. Hence, it becomes essential to recommend good practices to be followed by the users while warning about things to be avoided. Let’s have a look.
Some Common Things About Brass:
- Addition of Pb: Lead globules usually migrate towards the boundaries while casting. Hence, its content in brass increases the loss of materials during machining, and it particularly happens when the concentration of lead is comparatively low. In this way, the life of the brass part is significantly reduced by the addition of insufficient lead.
- Season Cracking: They are susceptible to Stress Corrosion Cracking. It means that Brass, being reactive to Ammonia, will be attacked chemically under high-stress environments. It leads to the formation of cracks. This problem can be solved by enclosing them in annealed cases relieved of residual stresses, especially when it is under tight and hot environment.
- Regulations on Lead Addition: Legal regulations in some places prohibit any of the Brass alloys that don’t have Lead to be mixed with Brass alloys having Lead. It is a mandatory regulation to be followed by Brass parts exporters and manufacturers because of the contamination and poisoning concerns.
Good Practices to Follow:
Top-quality Brass parts exporters do recommend a set of good practices to follow so as to expect longer life from the brass part. Some of them are:
- Clean the crevices regularly. They are the places where the tarnish and the residue from the polishing process accumulates.
- Do not aggressively polish the brass parts with abrasive materials. It gives a typical sheen to it called “butler’s finish’.
- Maintenance process for Brass is purely dependent upon the type of sheen and whether the part is lacquered or uncoated.
- Before beginning a large scale cleaning process, do document, photograph every part along with a written description for building archives.
Ultrasonic Cleaning Method:
One of the popular methods for cleaning intricate Brass parts is by using Ultrasonic waves. Herein, the parts are put in a basket submerged into a tank consisting of a suitable cleaning solution. Then, an appropriate cleaning cycle is decided that would get the most out of the process without affecting the material. The method is preferred for the following reasons:
- There is no need for dismantling the part in this cleaning method since it is submerged in a cleaning solution of very fine particles of size lesser than the tolerance between fastening arrangements in an assembly.
- The cleaning efficiency is almost a hundred percent in this method as the particles in the solution are exited into a high energy state and high-frequency oscillation so that they reach each and every crevice.
- Cleaning cost per piece is drastically lowered by this method since multiple parts are subjected to the process simultaneously. It saves time and money spent on overhead costs.
Manufacturers and Brass parts exporters recommend a wide range of standards for the maintenance and cleaning of Brass components, which guarantees a long life to the product.
