Use our lab capabilities and equipment to support your operations
Our lab is part of our ISO 9001 certified quality system. We use this lab to support our own brass and bronze manufacturing efforts as well as in support of our customers with their brass selection, testing, and standard compliance.
The engineers in our quality department support our brass and bronze manufacturing production by:
- Conducting over 50,000 chemical analyses per year to ensure conformance of our product to Wieland Chase standards which are tighter than ASTM standards.
- Inspecting every load of purchased scrap to eliminate material containing contaminants to avoid any negative health, safety or quality issues.
- Testing mechanical properties of every batch of rod produced to ensure they meet or exceed the relevant ASTM standard.
- Providing analyses of process variables to comply with environmental standards.
The Wieland Chase lab offers it’s metallurgical expertise to its customers as well. Our services include:
- Conducting failure analyses
- Product characterization
- Alloy selection
We also offer the following test options, all of which are traceable to known certified standards
- X-ray Fluorescence
- Optical Emissions
- ICP Emission
Significance and Use
4.1 The Rockwell hardness test is an empirical indentation hardness test that can provide useful information about metallic materials. This information may correlate to tensile strength, wear resistance, ductility, and other physical characteristics of metallic materials, and may be useful in quality control and selection of materials.
4.2 Rockwell hardness tests are considered satisfactory for acceptance testing of commercial shipments, and have been used extensively in industry for this purpose.
4.3 Rockwell hardness testing at a specific location on a part may not represent the physical characteristics of the whole part or end product.
4.4 Adherence to this standard test method provides traceability to national Rockwell hardness standards except as stated otherwise.
Mechanical Properties Testing Options
Significance and Use
4.1 Tension tests provide information on the strength and ductility of materials under uniaxial tensile stresses. This information may be useful in comparisons of materials, alloy development, quality control, and design under certain circumstances.
4.2 The results of tension tests of specimens machined to standardized dimensions from selected portions of a part or material may not totally represent the strength and ductility properties of the entire end product or its in-service behavior in different environments.
4.3 These test methods are considered satisfactory for acceptance testing of commercial shipments. The test methods have been used extensively in the trade for this purpose.
Stress Levels Testing Options
1.1 This test method describes the technique for conducting the mercurous nitrate test for residual stresses in wrought copper and cast or wrought copper-based alloy products. This test method is intended to cover the mercurous nitrate test of certain copper-alloy products supplied in accordance with ASTM specifications prepared by Committee B05. This test method is not intended to be used on assembled parts.
Note 1—For any particular copper alloy, reference should be made to the material specification.
1.2 Units—The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determines the applicability of regulatory limitations prior to use. For specific precautionary and hazard statements see Sections 1, 6, and 7. (Warning—Mercury is a definite health hazard in use and disposal.)
We participate in various national and international standards organizations to keep our team up to speed on any industry changes as well as offering our experience and expertise as appropriate.
