Brass and bronze are copper alloys used for a variety of decorative and functional items. Depending on the type and content of other elements in the alloy and according to the conditions in which the object is located, oxidation of the surface occurs, layers are formed where there is no clear boundary between the required patina and when it is already unwanted pollution. Often, previous repair and renovation processes, especially various coatings, will leave their mark on the items. Sometimes the requirement is to remove all impurities except for the metal itself, other times the customer considers a certain patina to be a desirable added value of the historical object. With the help of a laser , it is possible to remove impurities such as dust, old coatings and oxidation layers relatively quickly and efficiently, and then, according to the method of mechanical cleaning, renovate the surface according to the customer's ideas. We always make sure that the original surface structure characteristic of the production method, such as casting, forging, chip machining, etc., is not disturbed. www.lsrservices.cz
