Key specifications

Type: High‑copper admixed amalgam alloy, non‑gamma 2 formulation.

Form: Alloy powder for trituration with mercury (often used at approximately 1:1 alloy/mercury ratio as per instructions).

Composition (approx.): Silver 43.1%, Tin 30.8%, Copper 26.1% (Ag‑Sn‑Cu alloy).

Mechanical properties: Extra high copper with high 24‑hour compressive strength (around 450 MPa range) and controlled setting expansion for tight margins.

Indications: Direct posterior restorations (e.g., Class I and II), cores and build‑ups where amalgam is indicated.

Advantages: Non‑gamma 2 phase for improved corrosion resistance, reduced marginal breakdown, and long‑term clinical durability.

Origin: Manufactured in Sweden (Nordiska Dental brand line).

ANA 2000 is a silver‑tin‑copper admixed alloy that reacts with mercury to form a high‑copper amalgam suitable for Class I and II restorations in posterior teeth. The non‑gamma 2 formulation improves corrosion resistance, reduces marginal breakdown, and delivers high 24‑hour compressive strength for clinically durable restorations. Its handling characteristics and setting profile support easy condensation, carving, and finishing in routine operative dentistry.
