Metal glue refers to adhesives used to glue metal to metal or metal to other materials. Metal glue is sometimes called metal adhesives or metal adherents.
Metal adhesives can be cured by heat, exposure to air and by ultraviolet light. Metal adhesives are used in construction, such as holding to objects together prior to welding, and to seal pipes and fasteners.
ISO Standards for Metal Glue
ISO 11339 outlines the T-peel test for metal adhesives. ISO 14676 describes the test method for measuring how well aluminum surface treatments adhere to metal glue through a wet-peel test.
ISO 9664 outlines the test procedure for verifying the tensile strength of metal adhesives used in construction. ISO 10354 describes the test for measuring how durable metal adhesives are using a wedge rupture test.
ASTM Standards for Testing Metal Adhesives
ASTM D891 outlines the tensile testing of metal adhesives. ASTM D950 describes how the impact strength of metal adhesives is tested under sudden loads. ASTM standard D1062 outlines the process of testing the cleavage of metal adhesives. ASTM D2293 gives the compression load test to verify the strength of metal adhesives.
ASTM D896-04 gives the standard practice of measuring how well metal adhesives resist chemicals. ASTM D903 refers to the peel strength test for metal adhesives. ASTM D1151 outlines the standard method of measuring the effect of moisture and temperature on metal adhesives. ASTM D1184-98, published in 2012, outlines the method of determining the flexural strength of metal adhesives.
ASTM D1780-05 is the creep test for metal adhesives. ASTM D2295-96 describes the high temperature shear loading test of metal adhesives. ASTM D3310-00 is the standard test for measuring how corrosive the adhesives are. Metal adhesives can corrode copper and other metals.
Metal bonding adhesive testing via artificial aging in the lab is addressed by ASTM D1183-03. While most adhesives are not intended to conduct electricity, their conductivity is determined by the test methods outlined in ASTM D1304-99. ASTM D1879-06 describes the test procedure for studying their reaction to exposure to ionizing radiation.
SAE Metal Adhesive Standards
SAE standard AMS 3920 gives the criteria for sandwich structures held together with metal adhesives. SAE J1523 is the standard method of determining the shear strength of metal adhesives used in automotive assemblies. First published in 1985, SAE J1523 revision A was released in 2012. SAE J1851 is the induction cure test for metal adhesives.
Military Standards for Metal Adhesives
Mil-A-47089 was the DoD standard for metal filled adhesives. MIL-A-8623 was the military specification for metal adhesives. The DoD has replaced with standard with those set by the ASTM.
European Metal Glue Standards
DIN 54455 is the German standard for testing the strength of adhesive bonded metal joints using a torsional shear test. BS EN 2443-1 is the British standard for testing the single lap shear strength of metal adhesives. The German version of this standard is DIN EN 2243-1.
Industrial Standards for Metal Adhesive Prep
ISO 17212 gives the recommended methods of preparing metal for metal glue application. ISO 17212 gives the recommendations for preparing metal prior to the use of metal glue. ASTM D2094-00 outlines the process of prepping metal bars and rods for adhesive testing.
