Bronze casting
Mercobronze is characterized as a bronze casting specialized in the production of bronze materials and parts for industrial, automotive, naval, aerospace and related areas.
The company uses three bronze casting methods prioritizing the Continuous Casting, which concentrates eighty percent of all material manufactured. In second place comes Centrifugation. Large bronze parts, in the most different alloys and designs and shapes are produced by the company according to projects and measurements provided by customers. A small part of the production is done in die and sand system. Keeping the old method in operation, in addition to keeping alive the company’s link with the beginnings of the art of bronze casting, has a didactic role in the training of new hired junior professionals.

Bronze casting
For those who research bronze casting on the internet, some tips are essential to direct the researcher to the expected purpose:
1. Do you want a raw material casting in bronze? Or parts for industries, machines, vehicles, etc.? Or home decorative objects and similar products?
- If raw material: the most appropriate way is to look for the type of material desired: Billet? Tube? Bar? Strip?
- If parts: go straight to the desired product. Bushing? Semi-bushing? Bearing?
- If a piece of decoration: search for the name of the piece.
2. For those who want raw material in bronze, learn about the method of production of the material: continuous casting, centrifugal casting or die casting (sand)? In this case, it is important to know that
- Continuous casting: Appropriate to manufacturing of materials with a geometric pattern, scale production, lower manufacturing cost, linear quality.
- Centrifugal casting: Appropriate for the manufacturing of special parts, capable of being produced using a mold, production of few units and cost compatible with that of a custom-made part.
- Die and sand casting: More traditional, expensive, slow, rudimentary and low productivity method, applied to produce both custom-made parts and parts with geometric patterns.
Bronze Factory
When talking about a bronze factory, a huge range of metal alloys is being covered, based on copper and tin, with the possibility of adding zinc, aluminum, antimony, tin, bismuth, nickel and lead, among many other elements.
What is done in a bronze factory is to expose copper (or chalcopyrite, malachite, etc.) and tin (cassiterite) to very high temperatures, adding potions of other minerals, until they become alloyed by the action of carbonic anhydride.
It is with bronze that primitive tools and weapons were made (spears, arrowheads and shields), artistic sculptures (such as those featured in history and art books) and musical instruments (such as the bells, which to this day are found in the steeples of churches around the world). When we refer to the bronze factory, we refer to a technique that started 3,000 years ago, which marked a period of history called the Bronze Age.
Characterized as one of the main bronze factories in our country, Mercobronze keeps alive in its culture the art and history of this metal that spans millennia and remains actively participatory in the process of building progress and transformations that man imposes on the surface of the planet.
Alongside bakers, tailors and potters, metallurgists constitute one of the oldest professions. Bronze casters are the pioneers in this production chain. Consequently they are considered the fathers of modern metallurgy.
Bronze continuous casting
Casting bronze by the continuous casting method consists of producing long bars, in square, rectangular, round or hexagonal shape. These parts, in general, are used as raw material in the manufacturing of parts and components of machinery and equipment, and may undergo two types of processes: rough (machining) or heating and pressing against molds (forging).
Continuous casting is done by pouring liquid metal, obtained from a mixture of minerals heated in a crucible, whose types and proportions are approved in internationally accepted standards. With each different formulation, in which a greater or lesser part of each component is added, a type of alloy is obtained, identified in international standards by means of specific codes and nomenclatures.
Calling the production process of bronze billets in bars as continuous casting aims to differentiate the modern and productive method from conventional production methods, in which liquid metal is poured into fixed molds, from which one part is extracted at a time.
Mercobronze supplies the market vertically when it comes to bronze casting, that is: it produces and sells raw materials in bronze (billets, bars, tubes, strips) in the most diverse alloys, as well as finished parts and components ready for installation and operation in the industries it is intended to.
