The B-75 penetrator is used to give sensitivity and the Model B load spring is employed to give light pressures.\u003c\/p\u003e\n\u003cp\u003eThis combination allows the user to test the soft range of many common materials. The graph below shows the range covered by the Model BB-75 Tester on copper. Results were derived from many samples, and show the average curve. All tests were conducted with the Model BB-75 Tester set to read 17 on a standard test strip of 6061-T6 aluminum alloy of Rockwell E 90± 1 hardness. \u003cbr\u003e\u003cbr\u003eEach tester is shipped in a fitted case with a spare penetrator, adjusting wrench, and standard test strip. \u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch4\u003eWebster Hardness Testers\u003c\/h4\u003e\n\u003cp\u003eWebster portable hardness testers are made in three distinct models for testing brass, aluminum, copper, and mild steel. They allow you to quickly identify tempers and test a variety of shapes that other models simply cannot check - including tubing, extrusions, and flat stock.\u003c\/p\u003e\n\u003cp\u003eEvery one of Webster's hardness tester models operates in the same manner. The only differences are in the type of load spring, hardness ranges, and penetrator design.\u003c\/p\u003e\n\u003ch4\u003eModel BB-75 Webster Hardness Tester\u003c\/h4\u003e\n\u003cp\u003eCertain industries needed a method of rapidly testing the hardness of electrodeposited copper in the low hardness range. The Model BB-75 Webster Hardness Tester was the solution. This penetrator is used to give sensitivity while the Model B load spring is employed to give light pressure.

The work being tested is placed between the anvil and the penetrator. Pressure is then applied to the handles until the “bottom” is felt, then the dial indicator is read.\u003c\/p\u003e\n\u003ch4\u003eApplications for WEBSTER Hardness Testers:\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eCan Be Used on Assemblies That Cannot Be Brought to the Labs\u003c\/li\u003e\n\u003cli\u003eChecks for Proper Heat-Treatment Response\u003c\/li\u003e\n\u003cli\u003eDifferentiates Between Soft or Work-Hardened Material\u003c\/li\u003e\n\u003cli\u003eGives a Rapid 100% Check on Parts That Would Normally Take a Long Time to Test\u003c\/li\u003e\n\u003cli\u003eIdentifies Heat-Treated Parts\u003c\/li\u003e\n\u003cli\u003eIdentifies Parts Made from Improper or Substandard Alloys\u003c\/li\u003e\n\u003cli\u003eProvides Correlation Between a Bench-Mounted Hardness Tester and the Production Line\u003c\/li\u003e\n\u003cli\u003eSegregates Materials in Stock\u003c\/li\u003e\n\u003cli\u003eUseful in Conjunction with Stationary Laboratory Hardness Testing Tools\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eFeatures of Webster Hardness Testers:\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eCan Be Operated with One Hand\u003c\/li\u003e\n\u003cli\u003eEasy-to-Read Dial Indicator with 20 Graduations Permits Use as a “Go” and “No-Go” Gauge\u003c\/li\u003e\n\u003cli\u003eRound 3\/8-Inch Diameter Anvil Can Test a Variety of Shapes\u003c\/li\u003e\n\u003cli\u003eSimple Operation Permits Readings Independent of the Operator’s Skill\u003c\/li\u003e\n\u003cli\u003eTests Materials Up to 1\/4 Inch in Thickness with Increased Capacities Available Up to 1 Inch\u003c\/li\u003e\n\u003cli\u003eTest Only Requires Applying Pressure to the Handles Until the “Bottom” Is Felt\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Qualitest","offers":[{"title":"Default Title","offer_id":47772161441969,"sku":"Webster-BB75","price":4799.99,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0733\/5211\/8449\/files\/WebsterHardnessTesterModelBforAluminiumAlloys1.png?v=1784984331","url":"https:\/\/testingcore.com\/products\/webster-hardness-tester-model-bb-75-for-copper","provider":"TestingCore","version":"1.0","type":"link"}
