AFFRI is expert in the research and design of high-tech solutions in hardness testers since 1954. More than 70 years of hard work. AFFRI workers have faced to a wide variety of challenges and are experienced in every field of application. The level of knowledge now achieved by AFFRI makes us the best solution.
HARDNESS TESTERS CREATORS SINCE 1954
70 YEARS OF TECHNOLOGY
OUR HISTORY…OUR WORK…
Affri is a pioneer in the world of hardness testing. A family company which has been designing hardness testers for more than 60 years, producing systems which have been milestones for hardness testing. Each improvement has been patented. The 100% Italian production assures high quality standard hardness testers as well as developing any customized project.
1954 – First portable Rockwell hardness tester
1966 – First automatic Rockwell hardness tester
1982 – First digital Rockwell hardness tester
1984 – Introduction of the Load Cell Closed Loop Affri System
1993 – First optical Brinell reading with zoom
2000 – First Master hardness tester for reference laboratories
2012 – First portable Vickers with camera
2013 – First portable tester conform to ASTM E18 / E10 and ISO 6506 / 6508
WHAT WE DO
Bench-top and portable hardness testers for Rockwell, Superficial Rockwell, Brinell, Vickers, Knoop, Shore and IRHD hardness tests. All our hardness testing instruments are conform to international hardness standards ASTM and ISO. We produce automatic hardness testers for industries like heat-treatments, steel shops, foundries, forges, oil and gas, automotive, aerospace, naval and more.
We have all hardness testing solutions for every metal, iron, steel, tempered steel, cast iron, aluminum, brass, copper, hardening, nitriding, cementation and induction. Hardness testers to test plastic and rubber as Shore and IRHD hardness test. Special and specific hardness instruments to test gears, rolled steel, bars, metal plates, coils, valves, tubes, aluminum profiles, motors, engines, forged products, shafts, bearings, bottles and more.
Affri produces universal hardness testers to have all scales Rockwell, Brinell, Vickers and more on one single hardness tester. Micro and Macro Vickers machines with fully motorized system to perform automatic hardness tests on hardened gradients and CHD Case hardness depth. Hardness tests in laboratory fully conform to the hardness standards ISO 6506-3, ISO 6507-3, ISO 6508-3, ASTM E18, ASTM E10, ASTM E384. Hardness tester calibration service for all machines. Certified hardness test blocks. Certified diamond indenters and ball indenters.
THE AFFRI SYSTEM
OUR GOAL IS ACCURACY
1. AUTOMATION
All operations are managed by a single drive including automatic contact with the test piece from any distance. Fully motorized and automatic, the test is not affected by operator influences and can easily be used by operator of every level.
2. CLOSED LOOP (AFFRI patent 1984)
The testing forces are applied by load cells produced in house and controlled in Closed Loop at a frequency of 1000 input/second (1 khz), assuring perfect linearity. Test load accuracy is not affected by any structural deflection, misalignment or vibration.
3. AUTO-COMPENSATION SYSTEM
When testing unstable samples or deflective parts, the AFFRI System will follow the sample and not lose contact. The top surface referencing design minimizes errors caused by anvilling problems associated with oil, dirt or scale. The R & R. data is at the top of its class.
4. SPEED
The first result is correct and absolute in any condition. Accurate measurements, at the first test, eliminate the need for multiple repeated tests with no need to take the average. The Affri system increases both accuracy and speed with the consequential reduction of the testing time to the minimum. Saving time means saving costs!
5. CLAMPING SYSTEM
Secure contact with the specimen and perfect stability is always maintained, even in the unlikely event of any specimen movement during the test cycle. No additional accessories are required. The clamping protects the indenter, which moves down after the test piece is clamped thereby minimizing the risk to accidental shock.
6. BIG BASE
A wide and stable work holder plate to support masses beyond 2000 kg / 4409.2 lb eliminates the anvil instability problems, maintenance and adjustments. For large or very irregular test pieces which cannot be easily received by the regular bench hardness tester. Also, it offers a comfortable working area for small pieces.
