Keller’s Reagent for Aluminum Etching

Keller’s Reagent is the industry standard and most widely recommended etchant for the metallographic examination of aluminum and titanium alloys. Unlike Nital, which is used for ferrous metals, Keller’s Reagent utilizes a carefully balanced tri-acid mixture to effectively penetrate the natural oxide layers of non-ferrous materials.

This provides a high-contrast, exceptionally clear view of microstructural features. Whether you are analyzing cast aluminum parts, aerospace-grade titanium, or extruded non-ferrous profiles, our Keller’s Reagent ensures accurate, repeatable, and easily documentable results for your quality control laboratory.

Certified ASTM E407 Compliance

Accurate phase identification and grain size measurement require strictly standardized reagents. Gündüz Kimya manufactures our Keller’s Reagent in absolute strict adherence to ASTM E407 (Standard Practice for Microetching Metals and Alloys).

Keller’s Reagent Applications & Uses

Our Keller’s Reagent is precisely optimized for the most demanding non-ferrous metallurgical tasks:

  • Aluminum Alloys: The standard etchant for all series of aluminum alloys (cast and wrought). Excellently reveals grain boundaries, dendritic structures, and constituent intermetallic particles.

  • Titanium Alloys: Highly effective for general microstructural evaluation of commercial purity titanium and alpha-beta titanium alloys (such as Ti-6Al-4V).

  • Heat Treatment Verification: Clearly delineates precipitate phases to verify the effectiveness of solution heat treatments and artificial aging processes.

  • Weld Examination: Provides high contrast for the macroscopic and microscopic evaluation of non-ferrous weld joints, revealing the fusion zone and Heat Affected Zone (HAZ).

Keller’s Reagent Flexible Packaging to Suit Institutional Demands

Due to the highly reactive nature of the acids in this formulation, our Keller’s Reagent is packaged in specialized, chemically inert, non-glass polymer containers designed for maximum safety:

  • 250 ml Bottle: Perfect for specialized research, academic laboratories, or low-volume testing requirements.

  • 500 ml Bottle: The standard configuration for daily laboratory workflows and routine aluminum/titanium quality inspections.

  • 1 Liter (1000 ml) Bottle: The most economical option for high-capacity foundries, aerospace manufacturers, and large-scale industrial laboratories.

Why Choose Gündüz Kimya’s Keller’s Reagent?

  • Exceptional Purity: Compounded using strictly analytical-grade reagents and highly purified distilled water to prevent sample contamination.

  • Ready-to-Use Safety: Professionally pre-mixed to exact stoichiometric specifications. This completely eliminates the extreme, life-threatening hazards associated with laboratory personnel handling concentrated Hydrofluoric Acid (HF) during in-house dilution.

  • Unwavering Consistency: Rigorous batch-control guarantees identical chemical performance across every order, securing the reliability of your historical testing data.

  • Specialized Storage: Packaged in high-density, acid-resistant containers designed specifically to safely store hydrofluoric acid blends without degradation or container failure.

Extreme Safety & Handling Warning:
Keller’s Reagent contains Hydrofluoric Acid (HF), which is exceptionally toxic and highly corrosive. HF burns are extremely dangerous and require specialized medical treatment (Calcium Gluconate). Do not store in glass containers. Extreme laboratory safety precautions are absolutely mandatory. Always use complete Personal Protective Equipment (PPE), including heavy-duty neoprene or nitrile gloves, a face shield over safety goggles, and a heavy protective lab coat. Use strictly under a certified laboratory fume hood. Please consult the comprehensive Safety Data Sheet (SDS) provided by Gündüz Kimya prior to use and ensure Calcium Gluconate gel is readily available in your first-aid kit.
