Aluminium Etching and Cleaning

Our aluminum etching services help assess grain size, prepare surfaces for Fluorescent Penetrant Inspection (pre-pen etch), and reveal defects that might compromise component integrity. We carefully control chemical concentrations, temperature, and immersion times to ensure consistent results while preserving structural integrity.

• Surface defect detection
• Grain size assessment
• Pre-penetrant inspection preparation (pre-pen etch)
• Surface cleaning for further testing

We test a comprehensive range of aluminum parts essential to your operations. Your housings, enclosures, sleeves, brackets, tubing, cylinders, spars, spacers, fittings, flanges, bushings, beams, adapters, sockets, nozzles, shear pins, tie rods, angles, levers, pistons, hinges, latches, spirals, shim blocks, seal housings, retainers, and more benefit from our specialized etching and cleaning methods. Our services address multiple industries and component sizes.

• Structural components: housings, enclosures, spars, beams, brackets
• Mechanical parts: sleeves, tubing, cylinders, pistons, tie rods
• Connection elements: fittings, flanges, sockets, nozzles, adapters
• Control components: levers, hinges, latches, retainers  

With Element, you benefit from our specialized chemical etching and cleaning processes using sodium hydroxide (NaOH) in precisely calibrated alkaline baths. We strictly follow recognized industry standards while delivering clear, actionable information on your aluminum components.

• Alkaline bath processing with sodium hydroxide
• Specification-compliant etching and cleaning
• Controlled chemical reactions for consistent results
• Full regulatory adherence under one roof

We maintain a thorough understanding of industry requirements so that your aluminum etching and cleaning meets (and often exceeds) certification guidelines. Our ongoing compliance updates mean you can focus on quality without worrying about regulatory gaps.

• Multiple aerospace specifications supported
• Industrial standards compliance
• Regular specification updates
• Documentation for regulatory submissions

Our laboratories use specialized chemical baths, calibrated measurement instruments, and advanced inspection systems, all complemented by proper waste treatment and environmental permits. Because we hold everything in-house, you have assurance that each step—from chemical handling to final documentation—meets the highest standards.

• Chemical processing baths
• Waste treatment systems
• Environmental control equipment
• Measurement and inspection instruments
