Metal Blocks (Density Blocks Set Of 4)

This set of four solid metal blocks—copper, brass, iron, and aluminum—provides a consistent 13 × 13 × 50 mm specimen for precise density, magnetic and material‑identification investigations. The blocks are color‑coded and together weigh 234 g, enabling repeatable measurements in physics, chemistry and materials‑science laboratories.

Product Specifications

Applications and Benefits:

• Measure and compare the density of different metals using identical dimensions.
• Demonstrate magnetic properties by testing iron versus non‑magnetic aluminum.
• Explore additional physical characteristics such as hardness, acoustic response, and thermal conductivity.
• Support hands‑on laboratory exercises in physics, chemistry, and materials‑science curricula.

Key Features and Benefits

• Uniform size (13 × 13 × 50 mm) ensures consistent volume for accurate density calculations.
• Four distinct metals provide a clear contrast in mass and magnetic behavior.
• Durable solid construction allows repeated use over many years.
• Color‑coded identification simplifies visual sorting and rapid setup.

Caution:

Handle with care as metal blocks may cause injury if mishandled or dropped. Keep away from small children and pets.

Specific Gravity Block With Hook

The Specific Gravity Block with Hook is a 32 mm metal cube used for demonstrating density and buoyancy in educational and laboratory settings. Each cube is made from a different metal—Iron, Zinc, Aluminum, Copper, Brass, or Lead—to show the unique density of each material. The cube comes with a brass hook attached by a threaded connection and measuring about 26 mm in length, making it easy to suspend the cube for testing.

Product Specifications

Applications and Benefits:

• Ideal for physics and science classroom demonstrations.
• Used in density and buoyancy experiments.
• Provides hands-on learning for mass and volume calculations.
• Demonstrates material properties through direct comparison.
• Includes a brass hook for easy suspension and measurement.

Caution:

Handle with care, as metal blocks can be heavy and may cause injury if dropped. The lead block should be handled with caution due to its toxicity; wash hands after handling and avoid ingestion or prolonged exposure.

Note: Cube weight is estimated using the formula: Weight ≈ (Density in g/cm³) × (Volume in cm³), where 32 mm = 3.2 cm and Volume ≈ 3.2³ ≈ 32.77 cm³. Actual weight may vary slightly.

Zinc Electrode, Flat, One Piece

The Zinc Electrode, Flat, One Piece is a high‑purity zinc sheet measuring 5 × ¾ in with a thickness range of 0.75 mm to 1 mm. It is stamped with the letters “Zn”, weighs 16 g, and is supplied as a single flat piece suitable for precise electricity and chemistry experiments as well as industrial die‑casting and alloy production.

Product Specifications

Applications and Benefits:

• Conduct controlled electrochemical reactions in laboratory electricity experiments
• Serve as a reactant or electrode in chemistry experiments requiring zinc
• Provide a reliable source material for zinc‑based die‑casting processes in automotive, electrical, and hardware industries
• Contribute zinc content for the production of alloys such as brass, nickel‑silver, and commercial bronze
• Suitable for inclusion in metal collection sets due to identifiable “Zn” stamping

Key Features and Benefits

• High‑purity zinc ensures consistent electrochemical performance
• Flat geometry and precise dimensions facilitate reproducible experimental setups
• Stamped “Zn” marking enables quick identification and inventory control
• Thickness range of 0.75 mm–1 mm balances mechanical strength with ease of handling
• Compact 5 × ¾ in size and 16 g weight allow easy storage and transport
• Malleable at 100 °C–150 °C, expanding usability for elevated‑temperature processes
• Compatible with a variety of industrial applications, including alloy formulation and die‑casting

Caution:

Zinc is brittle at ordinary temperatures but becomes malleable between 100 °C and 150 °C; handle with care, especially when working at elevated temperatures.
