Materials engineering — Hindalium composition for cookware and utensils: State whether the following statement is correct. “Hindalium is an aluminium–magnesium alloy that includes a small quantity of chromium.”

Introduction / Context:
Hindalium is a trade name commonly used in the Indian cookware and utensils market for an aluminium alloy optimized for forming, strength, and excellent anodizing response. This question tests recognition of the correct minor alloying additions associated with commonly marketed Hindalium compositions.

Given Data / Assumptions:

• Hindalium refers to an aluminium alloy family used mainly for utensils and anodized wares.
• The base system is aluminium–magnesium with small additions for workability and anodizing quality.
• The statement claims the presence of chromium as the notable minor addition.

Concept / Approach:
In utensil-grade aluminium alloys, magnesium improves strength through solid-solution hardening while maintaining good formability. To improve corrosion resistance and anodizing color uniformity, small additions like manganese and sometimes silicon are typical. Chromium is not a characteristic addition for the widely referenced Hindalium utensil grades; chromium is more associated with certain aluminium alloys for structural or corrosion purposes or with stainless steels.

Step-by-Step Solution:
Identify the core alloying system used in utensil-grade aluminium: Al–Mg with Mn as the common minor addition.Check if chromium is a standard addition for utensil-focused Hindalium: it is generally not; manganese is typical.Compare market usage and properties: good anodizing behavior and formability align with Al–Mg–Mn systems.Conclude that the statement mentioning chromium as the typical minor element is incorrect.

Verification / Alternative check:
Typical cookware alloys (for example Al–Mg–Mn families) emphasize manganese for grain refinement and anodizing consistency, not chromium.

Why Other Options Are Wrong:
Agree/Agree with nickel/Agree for aerospace: these introduce alloying elements that are not characteristic for utensil-grade Hindalium.

“Disagree; it contains manganese instead of chromium” gives helpful detail but the core True/False correctness is captured by “Disagree”.

Common Pitfalls:
Confusing Hindalium with stainless steels (which are chromium-bearing) or with specialized Al–Cr alloys not used for utensils.

Final Answer:
Disagree
