Colonial Metals Co. - Brass and Bronze Ingots

At our company headquarters in Columbia, Pennsylvania, the entire process - from buying scrap metal to melting, casting, testing, order fulfillment and shipping - is handled on site by our experienced, knowledgeable staff.

Rotary Furnace

Our furnaces consist of four rotary units ranging from 50,000 lb. to 120,000 lb. capacity. These furnaces are used for plumbing and hardware alloys.

Electric Furnace

Three coreless induction furnaces (2 - 6,000 lb. furnaces and
1 - 10,000 lb. furnace) are used for engineering alloys with low impurities. These alloys are used to produce critical parts from chemical pumps to naval submarine propellers.

Two small coreless furnaces (35 lb. crucible unit and 500 lb. tilt coreless furnace) enable Colonial Metals to produce hardeners, small lots of specialty alloys and custom chemistries for research and development.

Electric Arc Furnace

Colonial Metals is the only brass and bronze ingot manufacturer with a submerged electric arc furnace. Colonial Metals uses the arc to safely melt and recover low-grade copper scrap. As a result, we have closed our manufacturing environmental loop.

Quality Control Laboratory

Our laboratory has been designed to meet the requirements of a fast-paced production environment. Quality is an important part of our process and our facility is endowed with up-to-date equipment and techniques specifically developed to ensure a high level of quality for analysis.

The driving force of this GLP regulated facility consists of proficient professionals covering three shifts and ensuring the generation of accurate and reliable test data.

The instruments used are:

OES Sepctrolab S (Optical Emission Spectrometer) is the instrument used for 75% of our analysis, using programs for Cu-base, Zn-base, Al-base and Ni-base alloys

ICP Spectro Flame Modula (Inductively Coupled Plasma) a spectrometer that uses a very high temperature excitation source that vaporizes, excites and ionizes atoms. Over time we have developed a great number of quantitative applications to analyze or check the elements in different alloys, for both minor and trace concentrations.

XRF spectrometer (Rigaku ZXS 100e) our new acquisition, uses non destructive and reliable methods for qualitative, semi-quantitative as well as quantitative analysis.

Other tests performed:
  • Titrations
  • Electrogravimetric determinations
  • Physical testing
