PACE Technologies also offers a full line of metallographic testing equipment and consumables. Our corporate headquarters are in Tucson, Arizona USA.

Our founder and Chief Technical officer is Donald Zipperian, Ph.D. Dr. Zipperian has had many years of experience in the field of metallography and materials science. Previously he was the General Manager and New Product Development manager for Buehler Ltd.

PACE Technologies has from its beginning had a strong focus on International sales. Presently they have distributors in 25+ countries and in the part year they have sold and shipped product to 50+ countries. For a list of countries where PACE Technologies has distributors click on the following link:


PACE Technologies also offers technical solutions and provides a Web Page (, and describing the requirements, application, guidelines, trouble shooting guides and product lists for both the data storage and metallographic analysis industries. PACE Technologies was also the first metallographic supply company to offer e-commerce pages and still is a leader in customized e-commerce pages.


We specialize in metallographic specimen preparation equipment, consumables and technical support.

I have included some excerpts from our web pages.  For more detailed information please take a look at the following web pages:

Metallography is the study of a materials microstructure and can be considered an integral branch for metallurgical testing or for the field of materials science. Analysis of a material's metallographic microstructure aids in determining if the material has been processed correctly and is therefore a critical step for determining product reliability and/or for determining why a material failed. Metallurgy is primarily the study of metals, however, many of the principles used for testing metals applies to ceramics, plastics, minerals, computer chips and many other applications which may be more unique such as measuring the age of the fish population in a lake by statistically analyzing the thickness of the ear bone.

Metallography equipment
Proper metallographic specimen preparation is the key to obtaining accurate microstructural analysis. This is accomplished by minimizing damage initially by properly sectioning the specimen with a metallographic abrasive saw for most metals and larger samples, or with the use of a metallographic precision wafering saw for smaller or more delicate specimens. After sectioning the specimens are typically mounted in a plastic either using a castable metallographic resin such as an epoxy, acrylic or polyester or with a metallographic mounting press. Mounting makes the specimens easier to hold, as well as, to protect delicate edges or coatings. Metallographic grinding and polishing are required to remove the damage produced during cutting and/or to expose the area of interest. Metallographic etching is used to bring out the details of the microstructure when viewed with a metallurgical microscope.

Metallographic abrasive saws - most commonly use specialized abrasive blades ranging 10-inch to 16-inch. Metallographic abrasive saws are table feed or wheel feed cutters and are designed to have safety lock out switches. Metallographic abrasive saws are wet cutting saws which are designed to reduce burring of the specimen so as not to the metallurgical or metallographic structure of the specimen.

Metallography precision wafering saws - one of the most widely used small precision saws uses either thin diamond or CBN blades. Metallographic precision wafering saws range in speed and size, however, they all use some sort of micrometer for precise positioning of the sample to the blade.

Metallographic compression mounting presses - typically after sectioning or abrasive cutting the specimen is encapsulated in a metallographic mounting press so that the sample is easier to hold or to fixture in a polishing machine. Metallographic compression mounting presses apply both heat and temperature to form phenolics, epoxies or acrylic mounts. Castable metallographic mounting can also be accomplished with castable polyesters, acrylics or epoxy resins.

Metallography polishers - are used to remove the damage and deformation created during cutting. Grind and polishing is accomplished with a variety of abrasives. Metallographic polishers are either manual or automated with automation being preferred for consistency and ease of use.

Metallographic vibratory polishers - are used for polishing very difficult to polish materials. The metallographic vibratory polisher is an excellent machine for polishing soft materials such as aluminum, stainless steel, solder materials, refractory metals such as rhenium, niobium, and precious metals such as good and silver. Metallographic vibratory polishers are also the most efficient samples preparation technique for electron backscattered diffraction specimens (EBSD).

Metallurgical microscopes - are inverted reflected metallographic light microscopes.

Metallography microhardness testers - are frequently used to measure the hardness and case depth for heat treated parts. Metallography microhardness testers utilize either a Vickers or Knoop indenter to produce an indent at a specified load. The depth of the indent or the hardness is calculated by optically measuring the length of the indent with an optical filar.

Metallography Rockwell hardness testers - provide a measurement of the bulk hardness by applying a preliminary load to set the indenter and then the primary or full load for a specific dwell time. The metallographic Rockwell hardness is determined by the depth of penetration of the indenter. Indenters are either conical or ball types for metallographic Rockwell testers and depending upon the load and indenter scales range for soft to hard materials.

Metallography Brinell hardness testers - provide a measurement of the bulk hardness by applying a load to a ball indenter. Metallography Brinell hardness is determined by optically measuring the diameter of the ball impression in the specimen.

Metallography Image Analysis - is a method for quantifying metallographic features such as: grain size, porosity, phase analysis, metallurgical inclusions, nodularity, coating thickness and other metallurgical testing features. Metallography image analysis can also be used to measure and characterize the quality of welded joints.
